Nassau police ID Uniondale homicide victim as Tadeo Alvarado-Chavez, of Roosevelt

The Nassau County Police Department has identified the victim of a homicide found dead early Monday in Uniondale as Tadeo Alvarado-Chavez, 40, of Roosevelt.

Police had said they responded to a 911 call at 4:05 a.m. on Monday "for an aided" on Nassau Road.

Citing the ongoing investigation, police declined to provide additional details.

But police confirmed the victim, later identified as Alvarado-Chavez, was pronounced dead at the scene by a police medic — and confirmed Homicide Squad detectives are investigating.

Police finally opened the parking lot where the incident is believed to have started at about 12:45 p.m. on Monday.

One resident of nearby Roosevelt, Andre McLean, said he was familiar with the area and spoke from the parking lot Monday afternoon, telling Newsday: "This seems like an isolated incident. There's been some scraps but nothing more than fights and stuff."

Calls to businesses located in the strip mall shopping center either went unanswered or were not immediately returned Monday.

Police are asking anyone with information to call 911 or contact Crime Stoppers at 800-244-TIPS.
