Homicide detectives are appealing to the public for help in the investigation of the double murder of Dianna Mah-Jones and Richard Jones last week.

Police said the 65-year-old Mah-Jones and 68-year-old Jones were killed at the home near West 64th Avenue and Hudson Street on Sept. 26.

Police have yet to establish a motive in the slayings, and have said they cannot yet confirm whether the attack was targeted or random.

On Tuesday, investigators appealed for more information regarding the time period from noon on Sept. 26 and noon on Sept. 27 from anyone who live in the area bounded by W. 70th Avenue (to the south), W. 58th (to the north), Oak Street (to the east) and Granville (to the west).

This is the area police are asking for residents’ surveillance, dashcam or security footage.

“We think the public can play a role in solving this crime. Something as simple as dashcam footage from a vehicle driving through the area last Tuesday could help with this case,” said Vancouver police Cst. Jason Doucette in a release.

“We’re asking residents in the area to provide us with a copy of their security footage, and to check their property for discarded items that don’t belong.”
