The gunman who opened fire in a Colorado supermarket, leaving 10 people dead, was convicted of murder Monday, with a jury rejecting his insanity plea that claimed he was hearing "killing voices" at the time of the massacre.

Ahmad Alissa, diagnosed with schizophrenia, admitted to fatally shooting 10 individuals, including a police officer, at a King Soopers store parking lot in March 2021 in the city of Boulder.

However, his defense team argued he was not guilty by reason of insanity, claiming he was unable to distinguish between right and wrong during the attack, according to the Associated Press.

During approximately six hours of interviews, Alissa consistently mentioned to psychologists that he heard voices, including "killing voices," just before the shooting, the AP revealed.

However, forensic psychologist B. Thomas Gray testified that Alissa did not provide further details about these voices or whether they communicated anything specific.

On the day of the shooting, Alissa drove from his home in Arvada, a Denver suburb, and stopped at the first supermarket he found in Boulder. He opened fire on three victims in the parking lot before making his way inside the store.
