Edmonton homicide detectives are hoping to stir up memories that might help find the killer of young woman 25 years ago. 

"A plea will always bring in tips," said Det. Howie Antoniuk, "I've been on this unit for four years and every time there's a plea or a mention of something happening on a file, it inevitably jogs people's memories."

Melodie Riegel was last seen in the area of 107th Street and 102nd Avenue at around 10:00 p.m. on September 20, 1986.

The body of the 19-year-old was discovered the next day by chambermaid in a room at the Pan American Motel, which no longer exists, at 10630 Kingsway Avenue.

An autopsy determined she had been strangled.

The room was registered to a man named Bruce Stevens claiming to be from Grande Prairie, but police believe both details were fictitious.

The man had checked in to Room 320  at 11:00 p.m. the night Riegel disappeared.

Riegel, who went by the name Tasha, was approximately 5’2", 100 pounds with blonde hair.

She was last wearing a purple leather jacket, a blue and black turtleneck sweater, blue jeans and white boots.
