UPPER MARLBORO, Md.— A man convicted of killing his mother and stepbrother has been sentenced in Prince George’s County to 110 years in prison.

Quindell Mercer received the maximum possible sentence at a Circuit Court sentencing hearing on Friday.

He was convicted of two counts of second-degree murder and other charges for the August 2011 double-shooting.

Prosecutors say there was no clear motive for the killings, but that DNA evidence and an FBI handwriting expert connected the 35-year-old Mercer to the crimes.

Prosecutors say Mercer shot both victims and then positioned their bodies on a sofa to make it appear as if they were sleeping. Frank Arthur Harris, the husband and father of the victims, found the bodies.
