Boulder County District Attorney Michael Dougherty filed 43 new charges against Ahmad Al Aliwi Alissa on Wednesday, nearly a month after the 21-year-old reportedly went on a shooting at a King Soopers supermarket that killed 10 people.
Alissa had already been charged with 10 counts of first degree murder and one attempted murder in the attack.
He is now facing 33 additional attempts at first-degree murder, one count of first-degree assault and 10 counts of felony possession from a high-capacity banned magazine, according to an amended complaint filed by prosecutors on Wednesday.

Alissa’s attorney, public defender Kathryn Herold, said in the accused mass shooter’s first lawsuit on March 25 that her client needs a mental health assessment.
“Our position is that we cannot do anything until we are able to fully assess Mr. Alissa’s mental illness,” Herold said in court.
