Pizza-guy slay bust

Police on Saturday arrested a suspect in the Wednesday night shooting death of a deliveryman outside his Harlem pizza shop.

Luis Jaime was to be charged with the murder of Jose Alvarado. Jaime, 29, of Harlem, also faces assault, menacing and weapons possession charges.

Members of the NYPD Warrants Squad apprehended Jaime early Saturday after he was identified as the shooter, although it was not clear why he targeted Alvarado.

It’s believed the men were embroiled in an ongoing dispute when Alvarado was killed.

Surveillance video shows that Alvarado never suspected what was coming.

On the video, Alvarado, 37, coasts up to the front of the Amsterdam Ave. Papa John’s at W. 145th St. about 10:30 p.m. He hops off his bike, seemingly unaware of a man watching him from behind.

Two men appear to approach him from the street after he swings one leg off the bicycle. In the shadows, at the top of the frame, a hazy figure appears to lift his arm toward the pizza worker and the suddenly Jose Alvarado’s body goes slack and he falls to the sidewalk, his bike crashes on top of him.

The deliveryman was taken to Harlem Hospital, where he died.

Police sources said Jaime followed Alvarado to the Papa John’s before shooting him.

The victim’s sister, meanwhile, was left looking for answers.

“Why did the killer take my brother’s life away?” said his sister Carmen Alvarado, 39. “He didn’t have a chance to have a family and raise kids of his own.”

She said she couldn’t believe her brother’s life ended so brutally.

“He wasn’t a street guy. He was a hardworking man,” she said.

The sister said he had no family of his own, just her and his mom, to whom he regularly sent money in San Francisco de Marcoris in the Dominican Republic.

“He was a wonderful brother and a hardworking man,” she said.

She said he hadn’t seen his mother in 18 years, but he still supports her.

“Now, she’ll see him dead,” Carmen Alvarado said.
