Winnipeg Police have put out a renewed call for information in a missing persons case.

Thelma Krull disappeared three years ago. She was last seen July 11, 2015, in the East Kildonan area. She had gone for a walk at 7:23 a.m. and is believed to have walked from her residence in the Grassie area to Civic Park near Kildonan-East Collegiate; she arrived there around 8 a.m.

Constable Rob Carver said today the point of the renewed call is to remind the public the investigation is ongoing, detectives are working on it, and they're still receiving tips.

"Investigators were fairly clear with me this morning that these news conferences make a difference, that we do see an increase, and that's why we're doing them," said Carver.

Krull is described as Caucasian, 5'4", 170 pounds, with short dyed blonde hair with a purple streak. She was last seen wearing a reddish/orange t-shirt, black Capri style pants, a black fanny pack, and tan/brown hiking-style boots.

After putting out a call for information two years ago, police received a tip of a possible sighting of Krull on the day she went missing in the Kimberly Avenue area, east of Gateway Road. Krull was reported to be with a heavy set male, Indigenous in appearance, about 5'8", with a bowl-style haircut. Police say this information has formed a significant part of the investigation, and homicide investigators are still looking to identify the man.sketchAn artist's sketch of a male police are looking for in Krull's case
