COTTONWOOD, Ariz. (AP) — Police say a television show that featured the nearly two-decade-old killing of an Arizona teenager and her unborn baby helped lead to an arrest.

Cecilio Cruz was taken into custody Tuesday in Tucson on charges of second-degree murder and manslaughter. Police in the city of Cottonwood, about 100 miles north of Phoenix, say Cruz fatally shot his ex-girlfriend, 17-year-old Marisol Gonzalez, in the face in an alley on March 25, 1997.

TNT's "Cold Justice" aired the case in February. Police Sgt. Tod Moore says an investigative team from the show visited Cottonwood in October and helped review dozens of leads and conduct interviews.

A grand jury in Yavapai County indicted Cruz last week. He's being held at the Pima County jail on $100,000 bond. Messages left with the Pima and Yavapai county sheriff's offices to determine if Cruz has a lawyer weren't immediately returned.
