Alonso's six years at the district's helm make him one of the longest-serving big-city superintendents in the country.

Under Alonso's leadership, student enrollment and graduation rates increased as suspension and dropout rates dropped.

He said Monday that he is retiring to return home to New Jersey to care for his parents and to assume a professorship at Harvard University.

His last day will be June 30. Chief of Staff Tisha Edwards will serve as an interim CEO through the next school year while the School Board searches for a permanent successor.

"I can't pretend it's not difficult to be reviled and maligned," Martha Mullen told The Associated Press in a telephone interview Friday. "But any time you can reach across the divide and work with people that are not like you, that's what God calls us to do."

Tsarnaev, 26, was quietly buried Thursday at a small Islamic cemetery in rural Caroline County. His body had remained at a Worcester, Mass., funeral parlor since he was killed April 19 in a gunfight with police, days after the bombings that killed three and injured more than 260 in downtown Boston. Cemeteries in Massachusetts and several other states refused to accept the remains. With costs to protect the funeral home mounting, Worcester police appealed for help finding a place to bury Tsarnaev.

Mullen said she was at a Starbucks when she heard a radio news report about the difficulty finding a burial spot for Tsarnaev.

"My first thought was Jesus said love your enemies," she said.

Then she had an epiphany.

"I thought someone ought to do something about this and I am someone," Mullen said.

So Mullen, a mental health counselor in private practice and a graduate of United Theological Seminary in Dayton, Ohio, sent emails to various faith organizations to see what could be done. She heard back from Islamic Funeral Services of Virginia, which arranged for a funeral plot at the Al-Barzakh cemetery. "It was an interfaith effort," she said.

Mullen, a member of the United Methodist Church, said she was motivated by her own faith and that she had the full support of her pastor.

"Nobody is without sin," she said. "Certainly this was a horrific act, but he's dead and what happened is between him and God. We just need to bury his body and move forward. People were making an issue and detracting from the healing that needed to take place."

There was little talk of healing among Caroline County officials and the cemetery's neighbors, however.

Caroline County Sheriff Tony Lippa said late Saturday that officials had examined paperwork necessary to move Tsarnaev's corpse from Massachusetts for its Virginia burial, and the interment appears legal. But he said his small department lacks the money and personnel to provide round-the-clock stakeouts at the cemetery as deputies did Friday night, which passed without incident.

"The Sheriff's Office will offer the same amount of protection no more and no less to this site as any other cemetery in Caroline County," Lippa said in a press release, noting that the owners can hire private security to guard Tsarnaev's grave from vandals if they wish.

Lippa was unhappy that he was blind-sided Friday by the covert burial, and he wasn't alone. Even some people within the area's Islamic community were incensed that they were not consulted about the burial in advance.

Imam Ammar Amonette, of the Islamic Center of Virginia, said that his group was never consulted and that Mullen had reached out to a separate group, the Islamic Society of Greater Richmond.

"The whole Muslim community here is furious. Frankly, we are furious that we were never given any information. It was all done secretly behind our backs," Amonette said, adding that it "makes no sense whatsoever" that Tsarnaev's body was buried in Virginia.

"Now everybody who's buried in that cemetery, their loved ones are going to have to go to that place," he said.

The Islamic Society of Greater Richmond didn't respond to an email seeking confirmation that it was involved in the burial.

Some readers responding to online reports about the burial and Mullen's role were supportive, others sharply critical.

Jaquese Goodall, who lives less than a quarter-mile from the cemetery, was unhappy that Tsarnaev was buried there.

"If they didn't want him in Boston, why did they bring him all the way down here against our wishes?" said Goodall, 21. "I am worried because his people may come down here to visit and there will be a whole lot of problems from him being here."

Caroline County Sheriff Tony Lippa was concerned, too, that the grave site could become a target for vandals and a shrine for those who sympathize with Tsarnaev.

"I know of no Virginia law enforcement agency that was notified," Lippa said. "No one in county or state government was aware of this."

Floyd Thomas, the chairman of Caroline County's board of supervisors, considered Tsarnaev's possible burial a black mark against the county where President Abraham Lincoln's assassin, John Wilkes Booth, was cornered and killed 148 years ago.

"We feel as far as this particular burial is concerned, we feel the same way that most of the people in the county feel most of the way America feels. We're very angry over the bombing ... that's not something that's supposed to happen," he said.

"We don't want the county to be remembered as the resting place of the remains for someone who committed a terrible crime."

Peter Stefan, director of the Worcester funeral home where Tsarnaev's body was held, had some sympathy for the Caroline officials.

"What I really didn't care much for was the fact that the city or town wasn't notified," he said. "Once the family takes over, it's their responsibility. But there's a moral issue here."

Local officials asked Virginia Attorney General Ken Cuccinelli to look into whether any laws were broken in carrying out the hushed burial. If not, there's likely nothing they can do.

"If there were, I think we'd try to undo what's been done," Thomas said.

Lane Kneedler, an attorney who represented the Virginia Cemetery Association when the law was drafted to regulate for-profit cemeteries in the late 1990s, said private and church burial grounds are not regulated by the state and only have to meet local zoning requirements. He said that once a cemetery is approved and operating, only its owner controls who is buried there.

The cemetery where Tsarnaev is buried contains 47 graves, all covered Friday with reddish-brown mulch except for two that appeared newly dug and were unmarked. On one of the new graves lay a vase full of roses at one end and a single red rose at the other end. The other new grave was bare.

State police cruisers, county sheriff's cars and black unmarked sedans with their emergency lights concealed cruised back and forth past the cemetery, officers inside them eyeing everything for any sign of trouble as reporters on the ground and those in helicopters high overhead broadcast the gravesite's location to the world.

Meanwhile, Tsarnaev's death certificate was released Friday. It shows he was shot by police in the firefight the night of April 18, run over and dragged by a vehicle, and died a few hours later on April 19. Authorities have said his younger brother, Dzhokhar, ran over him in his getaway attempt.

Dzhokhar Tsarnaev was captured later and remains in custody. The brothers are accused of setting off two shrapnel-packed pressure-cooker bombs April 15 near the marathon finish line, an attack that killed three people and injured more than 260. The brothers are also suspected in the shooting death days later of an MIT police officer.

Their uncle, Ruslan Tsarni of Montgomery Village, Md., took responsibility for the body after Tamerlan's wife, Katherine Russell, said she wanted it released to her in-laws. He said his nephew was buried in the Doswell cemetery with the help of a faith coalition.

"The body's buried," he said. "That's it."

One of the devices is a high-end smartphone featuring a screen that allows for three-dimensional images without glasses, these people said. Using retina-tracking technology, images on the smartphone would seem to float above the screen like a hologram and appear three-dimensional at all angles, they said. Users may be able to navigate through content using just their eyes, two of the people said.

It's as if Jeff Bezos told his research and development department to just build a phone with all of the trendiest, craziest features and then figure out how to make it cheap. Those features are trendy and crazy for a reason, by the way. Can you imagine the possibilities of a glasses-free 3D handheld device? That puts smartphones in Star Wars territory, if you can imagine objects floating in the air above the phone like a hologram.

Sure it sounds cool, but Amazon's been enabling rumors like this for years now. Nearly two years ago, the Wall Street Journal affiliate AllThingsD reported , as the company sought to compete more directly with Google and Apple. Amazon had already shown prowess in the hardware sector with the success of the Kindle and Kindle Fire and there's , so a smartphone made sense as a next step. It was a heck of a rumor at a time when iPhone 5 speculation was owning the tech blogs, and Android was systematically gobbling up market share. However well placed, though, it was just a rumor. It wasn't too crazy to assume that Amazon .

This latest rumor serves a similar purpose. Regardless of whether its true or not, reports about Amazon developing a 3D screen for mobile devices is a direct affront on Apple's strategy — that is, if Apple's patent history is at all indicative of the company's future plans.

The Palma de Mallorca court said it had accepted the appeal against calling 47-year-old Princess Cristina for questioning in a case concerning the alleged embezzlement of public funds by her husband Inaki Urdangarin and his former business partner.

The court summons had been a first for a member of the king's immediate family.

The nearly three-year investigation centers on whether Urdangarin and his former business partner took advantage of their royal connections to funnel about 5 million euros ($6.5 million) in public funds that their nonprofit Noos Institute received into private businesses they also controlled.

The court accepted the prosecution's argument that there was insufficient evidence of the princess' involvement in the institute's dealings but said she could still be called to answer questions regarding possible tax fraud and money laundering if the investigating judge produces new evidence.

The summons had topped off a year of health and image problems for 75-year-old King Juan Carlos, once one of Spain's most popular figures, widely admired for his role in helping Spain return to democracy in the 1970s after decades of dictatorship.

The corruption case and other issues have eroded Spaniards' admiration for their royal family especially as a crippling economic crisis has widened the gap between rich and poor.

A poll published last week by the government-run Center for Sociological Research indicated the monarchy's popularity rating has plunged to unprecedented levels.

It said that on a scale from 0 to 10, those questioned for its April survey rated the royal family at 3.68, down from 4.89 in October, 2011, the last time the question was asked.

The Royal Palace declined to comment on the court ruling.

Sean Collier, who began working for Massachusetts Institute of Technology about a year ago, was found shot to death late Thursday in his vehicle in Cambridge, Mass. Police have said Collier was responding to a report of a disturbance when he was shot about 10 miles west of Boston.

His brother, Andrew Collier, has been working for Charlotte, N.C.-based Hendrick Motorsports since 2008. He works in the engine shop and is not part of the team that travels to the track each week.

"My thoughts and prayers with the Collier family, and I certainly know it's the same thing with everyone at Hendrick Motorsports," five-time Sprint Cup champion Jimmie Johnson said Friday at Kansas Speedway. "We're one big family and it's sad to see a teammate going through this."

NASCAR teams were already planning to honor victims of Monday's attacks, which left three dead and more than 180 wounded, during this weekend's races in Kansas.

Roush Fenway Racing plans to donate $100 for every lap the team leads to The One Fund Boston, which was set up to help people affected by the bombings. The team's three Sprint Cup cars will also carry "B-Strong" decals, done in Red Sox script, that have cropped up this week.

The race team is partially owned by Fenway Sports Group, which owns the Red Sox.

"When events occur such as what happened earlier this week in Boston, it is our nature to be overwhelmed with a variety of emotions," Jack Roush said in a statement. "To have to withstand an act of such senselessness and cowardice against innocent people is disheartening to us all. Our hearts go out to the victims and their families, as well as the entire city of Boston."

Carl Edwards, who drives for Roush, said he hasn't had a chance to put the events of Boston in perspective, but realizes how fortunate he is to be driving a car this weekend.

"I can't quite grasp what's going on, I guess the consequences of it, but any time you see that, for me personally, it makes you realize the world is a crazy place," Edwards said.

The three entries from Michael Waltrip Racing are showing their support by replicating the bib numbers worn by Boston Marathon runners on their cars.The change in font for the car numbers was approved by each of the team's sponsors.

"The news coming out of Boston this week was very personal to me," said Michael Waltrip, who ran the Boston Marathon in 2000. "I remember thinking about what a privilege it was to be able to participate and all the hard work it took to be there. When you can see those international flags flying in Copley Square, you know you are about to complete your journey.

"I know the joy those runners were feeling at that moment when their worlds changed."

Bowyer, who drives one of the Waltrip cars, said the bombings touched everybody in NASCAR, and that the replicating bib numbers was simply one way to show their respect for the victims.

"It's a tragedy and a shame that these things keep happening," Bowyer said. "Now that I hear about the Hendrick organization, it's sad. It's been a tough week for all of us."
