Las Vegas, NV (KTNV) -- Police have one suspect behind bars in the abduction and murder of a woman who'd been missing for weeks.
Now questions are being raised about whether the suspect's girlfriend could face charges.
Las Vegas police said Edward Kopp and Kathy Atteberry were renting from the victim, 53-year-old Sheila Linke, and believe Linke was murdered after she tried to evict them.
"We do believe there was an altercation, a verbal altercation that began first and ultimately it turned physical," said Lt. Ray Steiber.
After Linke was strangled, Kopp reportedly drove her body out to the desert and dumped it. While the arrest report said Atteberry helped move the victim's body, police said she's currently not facing charges.
"At this point, there is no probable cause to make an arrest pertaining to her with any involvement in the offense," said Lt. Steiber.
But detectives stressed the investigation is not over.
In the police report, Kopp initially denied any involvement, but eventually told detectives he "wrapped three loops of nylon cord around her neck and then a put a plastic bag over her head," after Linke came at him with a knife.
Officers said Kopp later buried the victim's body in the Arizona desert, after stopping for drinks at a local restaurant.
Police said they suspected foul play early on in the case, when the missing person's report was filed.
Kopp is behind bars, and scheduled to appear in court on Friday.
