Raleigh, N.C. — The residence where two people were killed over the weekend was operating as a brothel, Raleigh police said Tuesday. But they could comment if it was connected to a motive behind the slayings.

Meanwhile, investigators are still searching for two men believed to be responsible.

Marco Antonio Alvarez-Martinez, 19, and Gregorio Lopez-Estrada, 23, died of gunshot wounds as a result of a shooting at 316 Sunnybrook Road Saturday afternoon.

Two others, Aquillino Padilla-Meza, 26, and Angelica Avendano-Pereda, 20, were injured.

Investigators say two men fled the scene in a dark-blue minivan, believed to be a late '90s model with untinted or lightly tinted windows.

The first suspect was described as a Hispanic mam in his mid-20s, about 5 feet 6 inches or 5 feet 7 inches tall, with a thin build and light complexion. He had short, curly hair and was clean shaven. He wore a white T-shirt and blue jeans, and police described his clothing was described as “very clean.”

The second suspect was described as a Hispanic man in his mid-to-late 20s, approximately 5 feet 6 inches tall, with a very dark complexion. He weighs between 150 and 160 pounds. He had short, curly hair and was clean shaven. He wore a black polo-style shirt with yellow horizontal stripes.

Anyone with information about the shooting is asked to call the Raleigh Police Department’s Detective Division at 919-890-3555 or Crime Stoppers at 919-226-CRIME.
