PHILADELPHIA (PIX11) – A man suspected in the deaths of his girlfriend and ex-wife in New York has been arrested, authorities said.

Timothy Taylor, 35, was taken into custody Friday at a bar in the 1100 block of Chestnut Street in Philadelphia, according to the U.S. Marshals Service.

Taylor was named as the suspect in the death of his ex-wife, Bronx native Tishawn Folkes-Taylor. She was found dead on May 28 in her home in Schenectady, New York.

Taylor was also named as the suspect in the death of his girlfriend, 37-year-old Theresa Gregg, who was killed inside her Brooklyn apartment on May 13.

Gregg’s own children dialed 911 after finding their mom unresponsive in the apartment, bleeding from several puncture wounds, NYPD sources told PIX11 News.

Gregg was an officer for the New York City Department of Homeless Services.

“She was a hard-working mom, working for the city, helping the homeless, and being an advocate of the homeless,” said former DHS peace officer Juan Beltran.

Folkes-Taylor’s family told PIX11 News her three young children were home when their mother was killed in Schenectady.

“Her 6-year-old child witnessed her mother being taken from this Earth. They are devastated right now,” said Stephanie McGraw, a domestic violence advocate working with the Folkes-Taylor family.

Folkes-Taylor’s brother said his sister had an active restraining order against her ex-husband, and there was a history of domestic abuse. 

“Our thoughts are with the children who suffered through this horrific domestic violence, and hope they find some semblance of peace and closure in Taylor’s arrest,” said Eric Gartner, U.S. Marshal for the Eastern District of Pennsylvania.
