The Boulder, Colorado supermarket shooting suspect now faces more than 100 charges, including murder and attempted murder

• The suspect in a mass shooting at a Colorado supermarket in March faces 61 new charges.
• Prosecutors say Ahmad Al Aliwi Alissa opened fire at King Soopers grocery store, killing 10.
• He now faces over 100 charges related to the murder and attempted murder of dozens of people.

The 22-year-old Colorado man accused of carrying out a mass shooting at a Colorado supermarket was charged Tuesday with 61 new offenses, bringing the total amount of counts against him to more than 100.

Prosecutors allege Ahmad Al Aliwi Alissa opened fire at King Soopers grocery store in Boulder with a legally-owned, semi-automatic rifle, killing 10 people including a police officer. He already faced 54 charges stemming from the shooting, including first-degree murder and more than 30 counts of attempted murder.

On Tuesday, Boulder County District Attorney Michael T. Dougherty added dozens of new charges - including attempted murder and crime of violence sentence enhancers - related to eight civilian victims who were in the store at the time of the shooting, but were not killed.

"Based on developments in the ongoing investigation, the District Attorney's Office has determined that additional crimes and sentence enhancers must be charged in this matter," Dougherty said in a statement.

By adding the civilians who weren't killed in the case, prosecutors have now named 10 murder victims, 15 attempted murder victims who are civilians, and 11 law enforcement victims, including the officer who was killed.

If convicted of first-degree murder, Alissa faces a mandatory life sentence without the possibility of parole.

Alissa is being held without bail. His next hearing is scheduled for September 7.
