Man Kills Ex-Girlfriend, Self in Brea Parking Lot : Slayings: He climbed aboard her catering truck, shot her, then kissed her twice before committing suicide, police say.

BREA — A man climbed aboard a catering truck parked in an industrial complex Monday, fatally shot the driver--his former girlfriend--kissed her, paused, kissed her again and then shot himself dead, police and witnesses said.

The man, identified as Arturo Fernandez Martinez, 48, shot 23-year-old Gwendolyn Leon of Anaheim at 10:50 a.m. as they stood in the doorway of a Super Snacks Catering truck in the parking lot of Trico Lambert Center, a tidy complex of sales offices and small warehouses.

Fernandez Martinez walked up, climbed into the truck and, after a brief argument, shot the woman, police said.

Witnesses to the shooting said he then kissed her twice before turning the gun on himself. According to the woman’s co-workers, Fernandez Martinez had been following and harassing Leon for three weeks as she drove the truck on her assigned route.

Police had not released the names of either the man or the woman late Monday, but officials at Brea Community Hospital, where the man was taken by ambulance, and UCI Medical Center, where medical personnel vainly fought to save the woman’s life, confirmed their identities.

After Leon was shot, the large white truck rolled slowly forward, stopping when its front wheels jumped a curb and hit a small tree, witnesses said.

The steel step leading to the driver’s seat was covered with blood, and it was there that police said they found the gun. Inside, rows of neatly stacked bread and other lunch supplies could be seen.

Leon was pronounced dead three hours after the shooting, said Elaine Beno, a spokeswoman for UCI Medical Center.

Fernandez Martinez was dead on arrival at Brea Community Hospital, officials said.

Leon’s co-workers at Super Snacks said that in recent weeks a man would drive his car back and forth in front of the company’s Santa Ana plant waiting for Leon’s truck to leave on its route and would then follow her as she made her rounds.

She complained about this to fellow workers and told them recently that she was seeking a court order against the man she referred to as Arturo, who she said had been her boyfriend for a year.

“He would hang out front and give her a hard time after work,” said Claudio Longhi, Super Snack’s manager. “She was a real nice girl. People who talked to her (Monday) morning said she was happy and said she’d had a nice weekend.”

Witnesses at Trico Lambert Center said they heard little before the shooting began.

Jay Flowers, a North Hollywood machine salesman, was in his office 50 yards east of the truck when he heard a shot and looked up.

“I saw the van rolling forward and the woman’s head was hanging out, and all of this blood was running down the side door,” he said. “I was in disbelief. Then I saw the guy with the gun kiss her on the lips. Then he looked around to see if anyone was watching, and he kissed her again.

“Then some other guy came running up to see what happened,” he said. “But as soon as he saw the gun he turned and ran. That’s when the guy with the gun put (it) to his head and shot himself. I just moved here from Detroit a week ago, but I guess this stuff happens everywhere.”

Andrea Morgan, a data entry clerk in the center, was at her desk about 10 yards west of the truck when the shooting occurred.

“I saw this hand move suddenly and then I heard the shot,” she said.

“At first I didn’t think it was a shot, thinking instead it was the door slamming shut. But the (victim) was screaming hysterically and the truck moved forward and hit the tree. I just yelled: ‘Oh, my God.’ ”
