BALTIMORE—The suspect in a deadly weekend shooting at an indoor trampoline park in Maryland was visiting his daughter there when he shot his ex-wife’s boyfriend and fled, according to court documents.
Quinton Walker, 30, turned himself in to authorities less than two hours after the shooting, which unfolded around 7 p.m. Saturday at the Sky Zone in Timonium, a suburb north of Baltimore. The victim, 32-year-old Marcus Whitehead, died after being rushed to the hospital.
