Manitoba RCMP are hoping a new social media blitz will help solve a 30-year-old murder.

On Sunday, the Mounties started live tweeting from the perspective of 15-year-old Kerrie Ann Brown from Thompson, Manitoba.

Trevor brown still vividly remembers spending time with his little sister.

Brown said she was kind, considerate and loved playing games in front of the TV.

"She'd sneak up behind me and jump me and start wrestling with me cause she had to cause I was her older brother, So she had to Pearl Harbour jump me so to speak," Brown said via Skype from Thompson, Saturday.

On Oct.16, 1986, Kerrie Brown was supposed to sleepover at her best friend Nicole’s house, but at a party in Thompson that night, Kerrie’s ex-boyfriend showed up with a new girl.

Kerrie was upset and didn’t want to be there. She never made it to the sleepover. Brown's family never saw Kerrie alive again.

“We've all lived with depression since this,” said Brown. “The city was quiet and our house especially quiet."

Two days later, two horseback riders found Kerrie’s body along a hydro line north of the city.

She had been sexually assaulted and her body has been poked with sticks.

Three decades later, Manitoba RCMP hope to spark new interest in the case.

Trevor Brown said he believes there is still someone out there who knows who killed his sister.

“It's them we need to reach. It’s them we need to bring out of the wood work," he said.
