Now a quest is underway to find Tsarnaev a resting place in Massachusetts. But before, the body will undergo a second "independent" autopsy demanded by his relatives.
His parents in Dagestan decided not to fly the remains there for burial, said family spokeswoman Heda Saratova.
There is no gravesite yet for the 26-year-old, said Peter Stefan, the owner of the funeral home. If no cemetery is found after the second autopsy, he plans to ask the government to find a grave.
He read Tamerlan Tsarnaev 's death certificate to CNN over the phone Friday.
"Gunshot wounds of torso and extremities," Stefan said. "Blunt trauma to head and torso."
Authorities have said his younger brother may have run him over as they resisted arrest days after the marathon attacks.
Widow in hiding
Katherine Russell, Tamerlan Tsarnaev's widow, remained largely out of view this week inside her parents' home.
According to her attorney, Amato DeLuca, the 24-year-old widow knew nothing of plans to bomb the race, and reports of her husband's involvement came as an "absolute shock" to Russell and her family.
But two sources familiar with the investigation told CNN that she spoke to her husband after his picture appeared on national television as a suspect.
The nature of the conversation remains under investigation, but the sources said there was some concern that Russell spoke with her husband but did not call authorities who were still seeking to identify the men in the photos.
Times Square foible
Dzhokhar Tsarnaev has told investigators that he and his brother decided to try to bomb Times Square as they talked the night of April 18 in a Mercedes SUV they carjacked in Cambridge, Massachusetts.
They still had five pipe bombs and a "pressure-cooker bomb" left over.
But the plan dissolved, when the driver of the vehicle, whom they held hostage for 90 minutes, escaped and police were notified. The violent chase that cost Tamerlan Tsarnaev his life ensued.
The man, who CNN is describing only as Danny because of privacy and safety concerns, said there was a difference of personalities between the brothers.
Tamerlan Tsarnaev kept talking throughout the ordeal, barking out orders, detailing his hatred of Americans and asking Danny to remain calm.
"If you cooperate, I won't kill you," said Tamerlan Tsarnaev, according to Danny.
While the talkative Tamerlan took the lead during the carjacking, the quiet Dzhokhar responded to multiple orders, such as getting money from an ATM, he said.
Tsarni has claimed that a man known as "Misha" was responsible for radicalizing Tamerlan Tsarnaev. On Monday, a U.S. government official told CNN that FBI agents had interviewed Misha.
The man, whose real name is Mikhail Allakhverdov, denied ever encouraging a violent take on Islam and says he was not Tamerlan's teacher, according to a New York Review of Books writer who says he interviewed Misha.
Federal agents are also looking into possible links between Tamerlan Tsarnaev and a Canadian boxer-turned-jihadist killed by Russian troops in 2012, a source being briefed on the investigation said. William Plotnikov and six others died in a firefight with Russian forces in Dagestan in July 2012, while Tsarnaev was visiting the region, the source said.
Of the scores of people injured in the blasts, 12 remain in five Boston-area hospitals, though none is in critical condition, according to information the hospitals provided to CNN.
