TULSA, Okla. (AP) — Prosecutors say DNA evidence led to first-degree murder charges against two people for their role in the slaying of a man found tied up and beaten inside a Tulsa hotel room more than 35 years ago.

First-degree murder charges were filed Friday in Tulsa against a 58-year-old Texas woman and a 61-year-old Wyoming man for the 1983 murder of Anthony Baltes. Arrest warrants were issued on Friday, and it was not immediately clear if the two suspects were in custody.

Investigators believe robbery was the motive, but the case grew cold.

Oklahoma Attorney General Mike Hunter says DNA technology advances allowed prosecutors to link the two to the crime.

Tulsa County District Attorney Steve Kunzweiler declined to elaborate on the DNA evidence, saying he looks forward to presenting it in court.
