Dallas Police arrested on Saturday the man who allegedly abducted and killed 18-year-old Zoe Hastings, who was on her way to church for Sunday school.

Antonio Lamar Cochran, 24, was taken into police custody after detectives discovered DNA evidence at the crime scene and matched it to his, according to the New York Daily News.

Cochran's DNA was already in the police data bank and his appearance matched the descriptions relayed by witnesses, Maj. Max Geron from the Dallas Police Department said.

The police had been trying to track down an unidentified black man who was seen talking to Hastings at a Walgreens drug store on the day she was killed.

Geron added that Hastings did not know Cochran and what motivated him to allegedly abduct and murder her remains unclear. "He is obviously a sexual predator that's been taken off the streets," Geron said, the Daily Mail U.K. reported.

Hastings was found dead in her crashed minivan on Oct. 12 while she was on her way to the Church of Jesus Christ of Latter-day Saints for Sunday classes.

Her parents reported her missing to the police after she did not show up and failed to return home. Her body was discovered by a man who was driving his daughter to school, HNGN previously reported
