Colorado supermarket shooter was sane when he killed 10 people, prosecutor says

BOULDER, Colo. — A mentally ill man carefully amassed the guns and ammunition to kill as many people as possible before pursuing and fatally shooting 10 people at a Colorado supermarket in 2021, proving he knew exactly what he was doing, a prosecutor told jurors Friday.

Ahmad Alissa’s decision to buy steel-piercing bullets and an optic sight that put a red dot on his victims, before firing multiple times at all but one of his victims shows he acted with intent and was not insane at the time, Assistant District Attorney Ken Kupfner said during closing arguments in Alissa’s trial. Everyone who was shot died in the attack.

Alissa, who has schizophrenia, has pleaded not guilty by reason of insanity in the attack at the store in the college town of Boulder. His attorneys acknowledge he was the shooter but say he was legally insane at the time of the shooting.

Mental illness is not the same thing as insanity under the law. In Colorado, insanity is defined as having a mental disease so severe it is impossible for a person to tell the difference between right and wrong.

Alissa fired his first shot at his second victim, Kevin Mahoney, in the parking lot after bracing himself on the hood of a car so he could take better aim with his semi-automatic pistol, which resembled an AR-15 rifle, Kupfner said. Alissa then pursued Mahoney as he tried to get back to the store.

“The defendant was tenacious and he was relentless,” Kupfner said.

During two weeks of trial, the families of those killed saw graphic surveillance and police body camera video. Survivors testified about how they fled, helped others to safety and hid. An emergency room doctor crawled onto a shelf and hid among bags of chips. A pharmacist who took cover testified she heard Alissa say “This is fun” at least three times.

Several members of Alissa’s family, who immigrated to the United States from Syria, testified that starting a few years earlier he had become withdrawn and spoke less. He later began acting paranoid and showed signs of hearing voices, and his condition worsened after he got COVID-19 in late 2020, they said.

Alissa’s mother told the court that she thought her son was “sick.” His father testified that he thought Alissa could be possessed by a djin - an evil spirit - and that his condition was shameful for his family.

His parents and some of Alissa’s siblings sat in the court gallery for the first time during the trial on Friday, just a few feet behind him. Relatives of the victims mostly sat on the other side of the courtroom.

Alissa is charged with 10 counts of first-degree murder, multiple counts of attempted murder and other offenses, including having six high-capacity ammunition magazine devices banned in Colorado after previous mass shootings.

Alissa started shooting immediately after getting out of his car at the store on March 22, 2021, killing most of the victims in just over a minute. He killed a police officer who responded to the attack and then surrendered after another officer shot him in the leg.

Alissa got an adrenaline rush and a sense of power from shooting people, Kupfner argued, though prosecutors did not offer any motive for the attack. Kupfner said Alissa first began searching for public places like bars and restaurants in Boulder to attack, before focusing his research on large stores the day before the shooting. Alissa pulled into the first supermarket he encountered as he entered Boulder on his drive from his home in the Denver suburb of Arvada, he said.

State forensic psychologists who evaluated Alissa concluded he was sane during the shootings. The defense did not have to provide any evidence in the case and did not present any experts to say he was insane.

However, the defense pointed out that the state psychologists did not have full confidence in their sanity finding. That was largely because Alissa did not provide them more information about what he was experiencing, even though it could have helped his case.

The experts also said they thought the voices he was hearing played some role in the attack and they did not believe it would have happened if Alissa were not mentally ill.
