OZARK, Ala. (AP) — A DNA match found through genealogy testing led to the arrest of a truck-driving preacher in the killings of two teen girls who were found shot to death in a car trunk nearly 20 years ago, authorities said Monday.

Coley McCraney, 45, of Dothan is charged with rape and capital murder in the 1999 deaths of 17-year-olds Tracie Hawlett and J.B. Beasley, officials told a news conference.

McCraney, arrested Saturday, is cooperating with authorities, a defense lawyer said.

Ozark Police Chief Marlos Walker said he knew McCraney from living in the same city and was surprised when DNA testing linked him to the slayings. He credited science, diligence and divine intervention with the arrest.

"I'm a spiritual guy, so it was all God's work," Walker said.

Hawlett's mother, Carol Roberts, said she went numb when she first heard of the arrest.

"We were just in shock," she said. "We still have a long road ahead of us."

The girls left Dothan the night of July 3, 1999, to attend a party, but never arrived. They were found the next day in the trunk of Beasley's car alongside a road in Ozark, a city of 19,000 people located about 90 miles southeast of Montgomery. Each had a gunshot wound to the head.

"I hope you understand that two victims in this case were not forgotten," Alabama Attorney General Steve Marshall said. "Cases are not forgotten. Cases are not filed away."

A different suspect was cleared after his DNA didn't match that from semen found on Beasley.

A judge had ordered McCraney to submit to DNA testing less than a month after the slayings because a woman filed suit claiming he was the father of her daughter, court documents show. But he failed to submit a sample and was ordered to pay child support.

Last year's arrest of "Golden State Killer" suspect Joseph DeAngelo in California — in which genealogy testing helped identify the suspect — was a factor in prompting the small Alabama police department to send their evidence to Parabon NanoLabs in Reston, Virginia, for DNA analysis, Walker said.

Walker described three rounds of genetic testing that led to McCraney's arrest. The first gave authorities an unknown suspect and then a genetic genealogy test identified a family. Kinship testing "ultimately narrowed it down to a single person," Walker said.

District Attorney Kirke Adams said he would seek the death penalty. The multiple capital charges against McCraney include one of killing Beasley during a sexual assault, he said.

"I've been doing this job a long time, and here's my concern: social media convicts him before we've ever seen the evidence, and that's troubling to me," McCraney's lawyer, David Harrison, told The Associated Press on Monday.

"It's going to be difficult to find a jury that's not already aware of the facts," he added. "I might have to ask that it be moved to another venue to get a fair trial. A lot of emotions are flying."

Harrison said McCraney is an outstanding member of the community and a married man with children and grandchildren. He's been a truck driver and had his own church where he preached as recently as three weeks ago, Harrison said.

"My heart goes out to the victims' families," Harrison said. "It's a tragedy. We don't need to make it make three tragedies by convicting him."
