GIBRALTAR (WWJ/AP) – Authorities tentatively have identified the remains of a woman found stuffed in a suitcase and floating in a creek as a 32-year-old southeast Michigan woman.

The victim is likely Pamela Prpich, who went missing Aug. 12 from Bella Vista Condominiums along West Jefferson near Gibraltar Road, where she was living with her mother.

Gibraltar Police Chief Ray Canterbury said they have been searching for evidence since the remains were discovered on Thursday night.

“The brother of a girl who was reported missing on Monday called us, made the report, and she had been missing since Friday. Nobody had seen her since Friday,” said Canterbury.

Police say Prpich’s brother had been looking for her and was alerted to the suitcase by people boating on the creek, about 20 miles southwest of Detroit. He opened the suitcase Thursday night.

Canterbury said investigators feel “it’s a pretty good chance” the body is that of Prpich, but they won’t be able to positively identify the victim until DNA testing is complete.

No one is in police custody.

The body was dismembered.
