Autopsy results released Friday by Rapid City Police Department indicate gunshots caused the deaths of Deb Ohlmacher and Brad Swanson, who died in what police are calling a murder suicide.
Police say Swanson, 58, killed 55-year-old Ohlmacher and then himself late Tuesday night on Woodrun Lane, on the city's west side. Authorities say the two had been involved in a rocky romance.
Police spokeswoman Tarah Heupel said toxicology results are expected back in a few weeks, and the investigation is ongoing.
Ohlmachers' three dogs are being cared for by family members, she said.
