Monica Brown, 38, was found fatally shot in her car parked outside her home on the 2300 block of Olson Street in Temple Hills, Maryland, in the predawn hours of May 17, 2006. Friends reported she had attended a church service shortly before her death, which frames the last known movements in a way that adds poignancy to the case.

Prince George’s County police opened an investigation and interviewed family members as they worked to establish a motive and identify who killed Brown. At the time authorities had no suspects in custody and had not determined a reason for the killing. There have been no public announcements of arrests or identified suspects since the initial inquiry.

Does anyone who lived in Temple Hills in May 2006 or who knew Monica have information that could help investigators?
