Kenneth Feinberg, administrator of The One Fund Boston, told CNN's Don Lemon that while the amount of money might sound substantial, "you have to dampen expectations."
"I doubt anyone will be made whole by these allocations," he said.
"No amount of money distributed fairly quickly over the next month or two is going to provide the type of long-term financial stability" needed by a double-amputee or somebody hospitalized with a brain injury, Feinberg said. "There's just not enough money for those purposes."
4. Residue in the kitchen sink
Federal authorities on Sunday searched Tamerlan Tsarnaev's apartment, the home he shared with his wife, Katherine Russell, and their young daughter.
It was not immediately clear whether investigators had taken anything from the apartment Sunday.
But on Friday, a source briefed on the investigation said law enforcement officials found explosives residue in the small apartment.
The source said the residue turned up in at least three places: the kitchen table, the kitchen sink and the bathtub.
Dzhokhar Tsarnaev has said the two brothers built the bombs in the apartment, U.S. law enforcement officials briefed on the investigation have said.
Russell, the widow, has remained largely out of view since her husband's death, staying in her parents' Rhode Island home.
Her attorney, Amato DeLuca, said 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.
5. Wrong place, wrong time, wrong people
Amir Ismagulov, the father of Azamat Tazhayakov, said his son was simply at the wrong place at the wrong time with the wrong people.
Tazhayakov and Dias Kadyrbayev, both 19, are accused of obstruction of justice after allegedly removing the laptop and backpack from Dzhokhar Tsarnaev's room.
If convicted, they could face up to five years in prison and a $250,000 fine.
Tazhayakov's father, who lives in Kazakhstan, told CNN in New York that he met with his son last week for about 40 minutes.
Both father and son believe in the U.S. justice system, Ismagulov said. The government will get to the bottom of what happened and let Tazhayakov go, the father said in Russian.
Teenagers sometimes do stupid things, Ismagulov said, stressing that his son didn't know he was doing anything wrong.
