PUEBLO, Colo. (CBS4) – A man suspected in the murder of his pregnant girlfriend turned himself in to Pueblo police on Friday.

Joseph Romero, 56, was wanted in the death of Phenia Martinez, 25, who was eight months pregnant, police said.

Her body was found on Monday in a home the couple shared. She was reported missing last Friday after she didn’t pick up her children from school and missed a doctor appointment.
