BROOKLYN, N.Y. (CBS 2) — The search is on for a rooftop gunman who shot and killed a man who was on the job as a deliveryman, CBS 2’s Lou Young reports.

Additional detectives were assigned Tuesday to the investigation of Jorge Martinez’s murder in Brooklyn as his family prepares to bury him.

Jennifer Martinez, 16, wants to know who killed her father, firing a gun from a rooftop in Brooklyn Friday night, and how her family is going to pay for the funeral and transport of his body back to Ecuador.

“I want to bury him in peace. We want to bury him next to his dad,” Martinez said. “And we have a sister who died there, too, and we wanted them to be together.”

Jorge Martinez was the breadwinner, sending money back to his ex-wife and their two teenaged children.

The shots that killed him came through the roof of his delivery van has he drove by the Marlboro houses in Gravesend.

Police aren’t wild about using the term “sniper.” They say whoever shot Martinez was no marksman, but rather just someone taking pot shots at parked cars before hitting Martinez’s delivery van as it drove by.

The building the shooter shot from is old and has a known drug location on the top floor. A lot of residents are afraid to go out at night.

“It’s scary,” said Veronica Lopez, resident. “I want to move soon because I have a girl and I worry about it.”

She heard the shots, as did another resident who did not want his name released.

“I heard the shots,” he said. “But I didn’t think anything of it because they shoot all the time around here.”

Detectives are pressing hard, but having a difficult time identifying a suspect. Reward money is being offered for information.

Martinez’s son, Jorge Jr., turned 14 on Tuesday. He had planned to celebrate his birthday with his father.

“Everything he did, he did for us, like that night job, he did it for us because my birthday was today,” Jorge Jr. said. “So he could have money to take us out to eat and buy myself a present. I guess all I can do now is go to school and be, accomplish what I told him I wanted to be in the future.”

The wake is planned for Wednesday. Police have yet to make an arrest in the case.
