The plea stemmed from the Oct. 15, 2011, slaying of 47-year-old David Brown at their home, 582 E. Carmel Drive (7400 South).
According to testimony at an April preliminary hearing, Wiggins told police during a lengthy interview that he and Brown had several disputes during the four months they were roommates. Wiggins wanted the home cleaner for when his daughter visited and was angry that Brown worked at an alcohol treatment program but drank at home. There were also back-and-forth allegations about stolen property.
About 50 or 60 CDs disappeared two days before Brown's death and Wiggins was furious, according to testimony.
Wiggins returned to the home the day of the homicide to ask for the CDs again, got upset and left. When he returned, the locks had been changed.
Wiggins climbed a ladder to break into his bedroom, where he encountered Brown. The two argued until Wiggins threw a plate in Brown's face and the two began fighting, and Wiggins struck him several times with a rake handle, police said.
Police found Brown's body at the foot of the stairs.
A medical examiner determined that Brown died because his heart was enlarged, but the stress of the assault precipitated his death.
