PORTSMOUTH, Va. (AP) -- Police in Virginia have identified three people who were killed in a shooting Tuesday that also left a fourth person in critical condition.

Portsmouth police say the shooting happened shortly after 9:30 a.m. near the 1500 block of Maple Avenue.

The three victims have been identified as 30-year-old Georgio Davonta Lee, 37-year-old Oleisha Deanna Mears, and 34-year-old Ashley Merricks.

Police have released little information about the shooting and said they are working to identify suspects and a motive.

Police said a 66-year-old man remains in critical condition with life-threatening injuries.

Witnesses reported seeing a vehicle leaving the area, which police say may be a 2011 black GMC Acadia with Virginia tags VVF-9829.

The city has had a rash of shootings in the last week, including a fatal shooting on Monday, a separate non-fatal shooting Tuesday morning and multiple shootings last week.
