A Brentwood man was in police custody Thursday after fatally stabbing his cousin in Hauppauge and then stabbing his girlfriend's at her home in Brentwood, Suffolk police said.

Homicide squad detectives charged Wilson Felipe Andrade-Molina, 37, of Fairfield Circle, with second-degree murder and first-degree assault. He was held overnight at the Sixth Precinct and faces arraignment at First District Court in Central Islip Friday.

Shortly after 8 a.m., Suffolk police received a 911 call from the girlfriend of Andrade-Molina, reporting a woman had been stabbed at a  Charter Oaks Avenue address in Brentwood. 

Officers from the Third Precinct responded to the scene and found the victim with stab wounds throughout her body.

The female victim was identified by police as Santa Pena, 46, a cousin of the suspect and the sister of Andrade-Molina's girlfriend. She was transported to South Shore University Hospital in Bay Shore where she was listed in critical but stable condition, police said.

Andrade-Molina's girlfriend informed police that her boyfriend had confessed to stabbing her sister's boyfriend, who was also the suspect's cousin, police said.

Police received a 911 call at 9:45 a.m. from a man saying that he had found his employee fatally stabbed at his business on Oser Avenue in Hauppauge.

Authorities found the cousin, Luis Miguel Andrade-Cando, 38, with multiple stab wounds, and he was pronounced dead at the scene. Pena has the same address as Andrade-Cando in Brentwood.

"Wilson Felipe Andrade-Molina stabbed his cousin, Luis Miguel Andrade-Cando, at their place of employment ... at approximately 7:30 a.m. Andrade-Molina drove to ... in Brentwood and stabbed Andrade-Cando’s girlfriend, Santa Pena, at approximately 8:05 a.m.," a police release said.

Police found Andrade-Molina soon after on Gibson Avenue and Bay Street in Brentwood, where he was arrested and taken into custody.

"This is a horrible incident," Suffolk Police Commissioner Rodney K. Harrison told reporters. "This is something that affects the whole county."

No motive for the stabbings was disclosed.
