Migrant in New York suspected of killing roommate and Wendy’s coworker within hours of each other

A migrant is accused of stabbing his roommate to death and then killing a coworker - both within hours on the same night.

Rony Yahir Alvarenga Rivera, 22, was charged with one count of first-degree murder and two counts of second-degree murder in Nassau County, New York, according to ABC 7. Officials say the suspect is from El Salvador and has been in the U.S. illegally since he was 12 years old.

A 32-year-old woman was found dead at the Valley Stream, New York, home that she shared with Rivera, according to police. Her name has not been released.

Investigators say that the killing happened around 9 p.m. Thursday.

Around midnight, authorities responded to a nearby Wendy’s for a report of a person with a knife, according to ABC 7. When police arrived, they found a 42-year-old mother of two dead at the fast-food restaurant. That victim’s name has not been released but she was a coworker of Rivera at the Wendy’s.

The two victims had multiple stab wounds to the neck and torso.

As police investigated the Wendy’s homicide, a person called 911 saying a man needed help at a nearby 7-Eleven.

Officers responded to the store and found Rivera, who told them he had killed someone, according to the report. Investigators arrested the suspect and linked him to both murders.

Police have not released a motive, but described Rivera’s mindset on that night.

“To sum it up in one word, angry,” said George Darienzo, the Nassau County Police Department’s commanding officer of the homicide unit, according to ABC 7.
