A Long Beach resident apparently miffed that a man had stepped over his laptop got into a fistfight and stabbed the victim in the heart in Santa Ana, a prosecutor told jurors today, but the defendant’s attorney said there wouldn’t be enough evidence to show his client committed murder.

Logan James Cunningham, 29, is charged with murder with a sentencing enhancement for the personal use of a deadly weapon in the August 7, 2016, stabbing death of 40-year-old Jason Paul Torres of Costa Mesa near a Shell station at 710 East Dyer Road.

Cunningham and Torres were with other friends partying at a Santa Ana motel when “at one point the defendant told everyone in the motel room, ‘Don’t step over my laptop,’ and at one point the victim does that,” Senior Deputy District Attorney Keith Burke said in his opening statement.

Cunningham complained he was being “disrespected” when one of the friends, Deanna Kirk, said it was “no big deal,” the prosecutor said.

As Cunningham and Torres left the gathering, Kirk lent them her car, Burke said. A short distance from the motel, a homeless man heard the two arguing loudly in the car before it pulled over near the Shell station, he said.

The two got out of the car and began throwing punches at each other, but not landing any, Burke said. At some point during the 30-second struggle, Torres was stabbed “at least twice” in the chest, the prosecutor said.

The transient, Jeremy Hanson, heard Torres say, “You stabbed me. You stabbed me in the heart. You’re going to jail,” according to Burke.

The prosecutor showed jurors surveillance video of Torres staggering to the Shell station for help. Torres was taken to a nearby hospital, where he was pronounced dead shortly after arrival, Burke said.

Cunningham attempted unsuccessfully to retrieve Kirk’s car keys, and when he couldn’t find them, he ran back to the motel, where he told her that he had gotten into a fight, Burke said.

“The evidence is going to show he wanted to fight and that’s why he parked in that area,” which was unlit and dark, Burke said.

“At some point during that, the defendant pulled out a knife and stabbed Jason Torres in the heart,” he alleged.

Instead of running to the gas station to get help or calling police, Cunningham ran back to the motel, where he told Kirk he lost the keys to the car but failed to mention the stabbing, Burke alleged.

Police traced the car back to Kirk’s mother, which led them to Cunningham as a suspect, the prosecutor said. Police also found Cunningham’s cell phone in the car, he said.

Police arrested Cunningham at his parents’ home in Long Beach, where they found an online article about the stabbing on a computer monitor, Burke said.

Cunningham “brought a knife to a fistfight,” Burke said. “And he had no legal justification to do that.”

Cunningham’s attorney, Ernest Eady, said jurors are unlikely to ever hear what started the fight and “who did what to whom, and what crime is it.”

“When you do get to the end of this case and you hear all the evidence, you will not find that this rises to the level of a murder,” Eady said.
