It was four years ago today that Cortney Lake was last seen alive.

Dashcam video shows the 24-year-old woman getting into a black pickup truck just before 8 p.m. on June 7, 2017.

The truck then pulls an aggressive U-turn on Michener Avenue in Mount Pearl and speeds away.

That truck belonged to ex-boyfriend Philip Smith, who killed himself five months later near Bellevue Beach where his family had a cabin.

Police believe Lake was murdered, and have said Smith was the only suspect in the case.

He already had numerous charges and convictions involving violent acts against her.

Lake’s mom, Lisa Brenton-Lake shared a post in the Facebook group Help Us Find Cortney marking the four years since her disappearance. Brenton-Lake is pleading with anyone who may have information to come forward anonymously.

Cortney Lake’s family has said they believe Smith’s friends have information that could help find her body, but instead continue to cover for him.

Searches to date have failed to yield any results.
