Ahmad Al Aliwi Alissa was convicted by a jury of 10 counts of murder at a Colorado supermarket. His defense team had argued he was mentally ill.

BOULDER, Colo. – The mass killing of 10 people at a King Soopers supermarket here in 2021 was carried out by a man whose mental illness neither qualified as insanity nor prevented him from carefully planning an attack he knew was wrong, prosecutors told a jury on Friday.

The jury trial hinged not on whether Ahmad Al Alissa opened fire but whether the mentally ill man understood the difference between right and wrong.

The man who killed 10 people in a mass shooting at a Colorado grocery store in 2021 was convicted on Monday of first-degree murder and sentenced to life in prison without the possibility of parole.

A Colorado jury on Monday found Ahmad Al Aliwi Alissa guilty on all counts in the March 2021 mass shooting at a King Soopers supermarket in Boulder County that killed 10 people.

Ahmad Alissa was convicted on charges that included 10 counts of first-degree murder and 38 counts of attempted murder.
