WYOMING, MI -- Dash cam video released by Wyoming Police shows the brief pursuit of a man suspected in the homicides of a Grand Rapids couple and their unborn child.

The July 17 police chase of 31-year-old Brady Oestrike, who shot and killed himself after crashing on an entrance ramp to U.S. 131, began when he fled while police were preparing a search warrant for his home on Taft Avenue in Wyoming.

An Internet task force's analysis of 18-year-old Brooke Slocum's computer showed she had arranged via Craigslist to meet Oestrike for sex in Gezon Park. Her boyfriend, Charles Oppenneer, 25, attended the meeting and was found dead and decapitated in Gezon Park on July 16. The pregnant Slocum was believed to be missing.

Police during the evening hours of July 17 briefly stopped Oestrike's yellow Chevy Cobalt on Burton Street near Burlingame Avenue SW. He drove off on Burton Street when officers approached.

The dash cam video does not show the crash on Burton Street and U.S. 131. The traffic stop and the tactical strategies after the collision also have been omitted by police.

Police said Oestrike killed himself after crashing.

Slocum was found dead in his trunk. Police said he held her captive since meeting the couple during the evening hours of July 12. A death certificate for Slocum says she died of ligature strangulation. Oppenneer's cause of death was listed as "homicide by unspecified means."
