Family wants second autopsy of Boston bombing suspect

(CNN) -- For nearly two weeks, Tamerlan Tsarnaev's body lay unclaimed at the Boston medical examiner's office. A funeral home now has the remains and a quest is underway to find him a resting place in Massachusetts.

But first, he will undergo a second "independent" autopsy demanded by his relatives, a family spokeswoman said.

Other hurdles remain.

His death certificate has yet to be filed with the Boston city clerk, and there is no burial plot yet, according to the funeral home holding the remains.

If no grave site is found after the second autopsy, Peter Stefan, the owner of the funeral home, plans to ask the government to find a grave.

Three cemeteries that Stefan contacted said they feared reprisals, but the funeral home owner said you can't pick and choose when it comes to a burial.

"This is what we do in a civilized society, regardless of the circumstances," Stefan said. "As I told some of them, at the immediate moment you may fear (reprisal), but later on, when things calm down, people are going to resent you because you didn't do it."

Tsarnaev died on April 19th after he and his brother shot a university police officer to death, carjacked an SUV and hurled bombs at officers pursuing them, according to authorities.

A few days earlier -- April 15th -- he and his younger brother, Dzhokhar Tsarnaev, allegedly bombed the Boston Marathon, killing three and wounding more than 260.

CNN obtained a copy of Tamerlan Tsarnaev 's death certificate, which lists the cause of death as "gunshot wounds of torso and extremities" and "blunt trauma to head and torso."

The document notes that Tsarnaev was shot by police and run over and dragged by a car. It lists the manner of death as homicide, and denotes that he was "DOA," or dead on arrival.

Authorities have said his younger brother may have run him over as they resisted arrest days after the marathon attacks.

Separately, 12 people remained hospitalized with bombing-related injuries on Saturday, according to a count by CNN. None were in serious condition.

Also, the frantic manhunt two weeks ago for the surviving bombing suspect drew the attention of gun rights advocates at their convention in Houston.

National Rifle Association Executive Vice President Wayne LaPierre said residents were "imprisoned" in their homes with no means to protect themselves while police searched for the younger Tsarnaev.

"How many Bostonians wished they had a gun two weeks ago?" he asked.

"Boston proves it. When brave law enforcement officers did their job in that city so courageously, good guys with guns stopped terrorists with guns," he said.

'Everyone deserves to be buried'

Tsarnaev's body remained unclaimed until Thursday, when an uncle, who had previously publicly condemned his alleged attacks, had a funeral parlor pick up the body.

The uncle, Maryland resident Ruslan Tsarni, had decried the alleged bombers as "losers" after the attacks.

Their parents in Dagestan have said they will not fly his body back to Russia for burial, spokeswoman Heda Saratova said.

CNN affiliate WCVB reported that the hearse that picked up Tsarnaev's body ferried it to a funeral home 30 miles away from Boston, near the Rhode Island state line.

Residents of North Attleboro, Massachusetts, took to the streets to boo Tsarnaev, when they heard about the presence of the corpse in their town, The Sun Chronicle reported.

Others took to social media to vent anger at the funeral home for accepting the body. It was later transported to Stefan's funeral home, Graham Putnam & Mahoney Funeral Parlors in Worcester.

"Everyone deserves to be buried," he said.

The marathon bombings

Authorities say the brothers carried out the Boston Marathon bombings using explosive devices made of pressure cookers.

Dzhokhar Tsarnaev, 19, is being held at a federal Bureau of Prisons medical facility in Devens, Massachusetts, charged with using a weapon of mass destruction, which carries the death penalty.

He is being treated for gunshot wounds to the head, neck, legs and hands that he received in the shootout with police that led to his brother's death.

Investigators found explosives residue in the apartment that the elder Tsarnaev shared with his wife and young daughter, a source briefed on the investigation said Friday.

It has turned up in at least three places at the small apartment in Cambridge, Massachusetts, the source said: the kitchen table, the kitchen sink and the bathtub.

Dzhokhar Tsarnaev has said they built the bombs there, U.S. law enforcement officials briefed on the progress of the investigation said.

Other target, a cover-up

The marathon was not the original target, the officials said. The brothers had set their sights on a suicide attack on the city's massive Independence Day celebration, which draws about 500,000 people and is televised nationally.

But the bombs were ready sooner than anticipated and a day or two before the Boston Marathon, they changed their plans, the officials said.

They spoke on the condition that their names not be used because they were not authorized to discuss the matter with the media.

One key question involves whether intelligence, law enforcement and homeland security agencies could have done more in their investigation of Tamerlan Tsarnaev in recent years before the attack and whether they shared information effectively enough. An independent government review is underway.

In an interview with Univision published on its website on Saturday, President Barack Obama said cooperation among agencies can always get better. But he again defended U.S. efforts.

"I think we can continue to improve and refine how we're engaging and countering terrorist activity," Obama said. "I don't think it's fair to say though that law enforcement dropped the ball."

It is very difficult to prevent attacks when dealing with individuals who are self-radicalized and not part of a massive conspiracy or network, he said about the current belief of investigators looking at the origins of the Boston bombing.

Tsarnaev's widow, Katherine Russell, has remained largely out of view since her husband's death, staying in her parents' Rhode Island home.

Her attorney, Amato DeLuca, says the 24-year-old knew nothing about plans to bomb the race, and reports of her husband's involvement came as an "absolute shock" to Russell and her family.

Three of Dzhokhar Tsarnaev's friends have been accused of covering for the bombing suspects.

Azamat Tazhayakov and Dias Kadyrbayev were charged Wednesday with conspiring to discard potentially incriminating items from Dzhokhar Tsarnaev's dorm room. Robel Phillipos was charged with making false statements to investigators.

The FBI is examining Dzhokhar Tsarnaev's laptop, two federal law enforcement officials told CNN.

Authorities have said they believe the brothers acted alone, but are investigating whether they could have learned from or have been aided by terror groups, including groups overseas.
