The gunfire on Cobbs Mill Lane erupted shortly before 1 a.m. A preliminary investigation shows that a person standing on condominium complex grounds fired the shots, which struck one unit, they said.
Residents told officers they heard the gunfire, followed by the sound of a vehicle speeding off, police said.
Witnesses or anyone else with information — including home surveillance video — are asked to contact Det. David Hoover at 860-652-4284. Tips may be left on the website, www.glastonburyct.gov/police, police said.
