NEW YORK (CBSNewYork) — A man walked into a pharmacy Thursday afternoon in Queens, handed his ex-girlfriend a bouquet of flowers and then pulled out a handgun shooting her twice in the back of the head, police said.

Guimmia Villia, 32, was working behind the counter at Crescent Chemists on 34th Avenue in Long Island City when 38-year-old Alex Figueroa walked in around 3:40 p.m. Co-workers said the two got into an argument before he pulled the gun on her.

The mother of two was pronounced dead at Mt. Sinai Hospital a short time later.

“You can’t make sense of it, it’s just very sad,” Judy, who knew the victim, said. “Everybody loved her, she’s an angel.”

“I think it’s disgusting to be honest with you, I don’t know how anybody can do that,” a man, who grew up with Villia in the Ravenswood Houses, said. “It’s sick.”

Friends said Figueroa was violent and had multiple orders of protection issued against him. Queens District Attorney RIchard Brown said Villia had got an order of protection against Figueroa in December 2009. It expired on Jan. 25.

Police found Figueroa dead in his Queens apartment from a self-inflicted gunshot wound.
