BOULDER, CO. – Ahmad Al Aliwi Alissa was identified by authorities Tuesday as the gunman who opened fire at a King Soopers grocery store in Colorado, killing 10 people, including a Boulder police officer.
The name of the 21-year-old suspect, who is in custody, was released at a news conference by Boulder Police Chief Maris Herold, who did not disclose a possible motive for Monday’s bloodshed.
A search of the suspect’s suburban Denver home turned up other weapons, a senior law enforcement source said Tuesday. The weapon used in the attack was an AR-15-style pistol modified with an arm brace, according to the source.
The warrant described Alissa as being armed with either an assault rifle or “black AR-15” and wearing a “tactical” or “armored” vest.
The suspect has been charged with 10 counts of first-degree murder and one charge of attempted murder, according to his arrest warrant. His first court appearance is scheduled for 8:15 a.m. (10:15 a.m. ET) Thursday, according to Colorado Judicial Branch online records.
Authorities believe Alissa was the only person involved and that there was no additional threat to the community.
Officer Eric Talley was the first Boulder police officer to arrive at the King Soopers store Monday afternoon. The 51-year-old quickly lost his life trying to save others.
Officer Talley is survived by his wife and seven children, his father said.
A verified GoFundMe account has been established to help Talley’s family.
