DNA and genetic genealogy have helped Michigan cold case investigators identify remains found in 1988 as those of a missing Oklahoma woman.

Michigan State Police refused to say Monday how 28-year-old Marcia Bateman of Oklahoma City died but said her death was suspicious.

Her association with prostitution and drugs could have “put her in contact with a lot of people that could potentially have caused something ill to happen to her,” Detective Sgt. Scott Ernestes told a news conference in Paw Paw.

Bateman had been reported missing by her mother two months before her remains were found in October 1988 along I-196 in Covert, according to reports. The last time her mother saw her was in May 1988.

“Through genealogy testing we were able to identify I-196 Jane as she had come to be known as Marcia Bateman,” Ernestes said, according to Fox 17 Grand Rapids.

He said the remains were identified in partnership with the DNA Doe Project.

Ernestes said Bateman bounced around Los Angeles, Dallas and Oklahoma City and got around by hitchhiking, MLive.com reported. She had no known ties to Michigan.

The sergeant said Bateman’s aunt was overwhelmed when told about the identification, the news outlet reported.

"She said it was really hard on her sister for many years, and she was always wondering what happened," he said.
