On March 1, 2010, 26-year-old Monica Sarah Botello and her two daughters, ages eight and six, were at a boyfriend’s house on Glastonbury Road in Detroit when two men forced their way inside. The intruders separated the adults and forced Monica and the children into an upstairs bathroom while they took the boyfriend, 26-year-old Purcell Carson, to the basement. The men returned and led Monica to the basement; the children heard gunshots from upstairs. After the assailants fled, the 8-year-old found Monica and Carson in the basement with their mouths and wrists bound with duct tape. Both had been shot in the head. The child used Monica’s cell phone to call 911 but Monica later died at the hospital; Carson was found deceased at the scene.

Investigators focused on two suspects, Derrick Dennard Smith and a second man, Devi Smith. A prison discharge slip belonging to Derrick Smith was recovered in a coat at the scene; he was apprehended in Gardena, California, and later convicted of two counts of first-degree murder and two counts of torture and sentenced to life without parole.

Did anyone in the Detroit area have contact with Monica, Purcell Carson, or the two girls around that March 2010 visit who might shed light on what brought the assailants to that house?
