The RCMP in Manitoba is trying an unorthodox strategy to solve a 30-year-old cold case — tweeting as the victim.

Kerrie Ann Brown was 15 when she walked out of a party in Thompson, Man., never to be seen again.

“There was a party that night and mom & dad said I could stay at my girlfriend’s house for a sleepover after.” #rcmpmb#kerrie — RCMP Manitoba (@rcmpmb) October 16, 2016

Police say she was raped, murdered, and dumped by the side of a horseback-riding trail in October 1986.

The RCMP has issued a series of tweets written from Kerrie’s point of view and hashtagged with her name.

The tweets chronicle her last day alive, dropping references to her favourite school subjects, her favourite of her brother’s endearing quirks, and the last meal she ate with her family.

“I stayed standing there, near the backdoor, to wait for her. My friend’s mom was the only other person around.” #rcmpmb#kerriepic.twitter.com/OUWMU7KElf — RCMP Manitoba (@rcmpmb) October 17, 2016

The tweets call on anyone with information on Kerrie’s death to come forward.

“There’s silence, but someone knows. Come forward. Stop being cowards. How are you able to keep what you did to me hidden,” asks one of the tweets. “What you did to me that night destroyed my family & friends. I didn’t do anything wrong. I was a happy 15-year-old girl.”

The RCMP did not immediately respond to request for comment on the approach.
