Surveillance video of the shooting death of Boston terror suspect Usaamah Rahim is expected to be played Monday morning during a briefing, a source with knowledge of the investigation said.
An official is expected to walk media through the events caught on camera, the source said.
Suffolk District Attorney Daniel Conley, Boston Police Commissioner William Evans and Vincent Lisi, FBI Boston special agent in charge, will also update media on the investigation into the fatal shooting, a statement from Conley’s office said. The briefing will be held at his office.
Police fatally shot Rahim last week after he allegedly wielded a military knife at counterterrorism officers.
His family members viewed the surveillance footage Thursday, and it seemed to calm their initial suspicions. The family asked police not to release the footage publicly until Rahim was buried Friday.
His brother, Ibrahim Rahim, originally posted to social media that police had killed Usaamah Rahim for no reason, shooting him in the back while he spoke on the phone with their father.
But after seeing the video, he acknowledged his initial post was not correct and asked the public not to jump to conclusions. He still wanted to know more about his brother’s death.
“The facts are still coming in. We need more information,” he said.
Counterterrorism officials have said they were monitoring Usaamah Rahim for at least a couple of years.
He “liked” an ISIS-related page on Facebook, and his social media posts demonstrated an admiration for radical Islam. While U.S. officials say they don’t believe ISIS helped him hatch a specific plan, a law enforcement official said the terror outfit influenced Rahim to a degree.
