Suspected Killer Turns Himself In for the Murder of Bronx Mom.

Just one day after we asked for help in identifying a man wanted in connection for a Bronx mother's death, he has turned himself in.

Asun Thomas, 46, from Brooklyn, turned himself in today after the NYPD released images of him in connection with the death of 40-year-old Luz Perez. Perez's body was found October 13th after her 5-year-old son crawled through security gates to alert passersby that him mom wasn't responsive.

Perez's young children, ages 5 and 2, had been alone in the house with her corpse for at least 27 hours before help came.

It was initially reported that the victim was stabbed with a screwdriver, but an autopsy concluded that Perez's cause of death was strangulation.

When Thomas surrendered to police on Tuesday, he told them he lived in a halfway house for homeless people in Brooklyn.

Records indicate that the suspect was released on parole in 2016 after serving 16 years out of a 20-year sentence for a 2000 manslaughter conviction.

It remains unknown whether Thomas knew Perez before the killing and just what his motive could have been.

Thomas is due in Bronx Criminal Court on December 30. He is being charged with murder.
