Boulder shooting suspect faces more charges

Colorado prosecutors have filed more than 40 additional charges against the suspect in last month's deadly grocery store shooting in Boulder.

"We're going to work as hard as we possibly can to reach the right outcome and to ensure that the shooter is held fully accountable," Boulder District Attorney Michael Dougherty said Thursday at a press conference.

Ahmad Al Aliwi Alissa, 21, allegedly opened fire and killed 10 people on March 22 in a King Soopers store and parking lot. A police officer who responded to the shooting was among the victims. Alissa allegedly legally purchased the semi-automatic Ruger AR-556 pistol used in the shooting only six days before the shooting, according to Boulder's police chief. 

Dougherty on Thursday outlined the charges filed against the defendant, saying they include nine counts of first-degree murder for each civilian killed in the shooting. In Colorado, the maximum penalty for murder in the first degree is life without the possibility of parole, Dougherty said. 

Dougherty said all nine victims were shot and killed before Officer Eric Tally and other officers entered the grocery store. The defendant's tenth count of first degree murder recognizes Tally's death.

Alissa also faces more than 20 counts of attempted murder of others and 10 counts of having a prohibited large capacity magazine.

Dougherty estimated that around 115 people were in the store at the time of the shooting and at least 25 people were in the parking lot. 

All of Alissa's charges can arguably run consecutively, Dougherty said. 

The suspect is currently in police custody at an undisclosed location after receiving death threats while at the Boulder County jail, CBS Denver reports. He has not entered a plea yet.
