TULSA, Oklahoma - Investigators have gone from holding out hope of finding a missing Tulsa woman alive to searching for her remains. Samantha Puckett, 29, has been missing for more than seven weeks.

Tulsa Police Homicide unit used search dogs to canvass a wooded area near her late boyfriend's home near Peoria and Apache.

Her boyfriend shot and killed himself December 21, 2016, moments before police entered his home with a search warrant. Flyers have been circulating since Puckett went missing, and police said she and the man who killed himself had been in a long-term abusive relationship. 

November 7 is the last time anyone saw or heard from the young mother.

"We're going to continue looking, and we're going to continue asking until someone tells us," said Sergeant Dave Walker, Tulsa Homicide.

Police said her boyfriend, who hasn't been named, is the only suspect.

"We're not looking that he had any help doing what doing what he did," Walker said. "There was a pattern of abuse in that relationship, and she didn't report it. We have evidence that he was very abusive to her."

With the man's death, police fear he took any evidence of Puckett's whereabouts with him.

Sergeant Dave Walker said they have information that have led them to taking this step, but they don't know if that information is credible. Investigators did an extensive search of his home following his suicide.

"We are doing a scavenger type hunt," Walker said. "We didn't find a man; we didn't find any remains; we didn't find anything that would lead us to a place."

Anyone with information on the whereabouts of Samantha Puckett please call Crime Stoppers at 918-596-COPS, the Homicide tip line at 918-798-8477 or email homicide@cityoftulsa.org.
