Tulsa police investigate four separate drive by shootings overnight Monday.
In each case, a shooter - or shooters - pulled up to north Tulsa homes and fired shots.
Police found bullet casings in the street in front of two houses near 2400 N Boston Place just after 3:00 a.m.
An officer told KTUL.com that the same car targeted two homes, one across the street from the other.
No one was injured in any of the incidents. Police say they have no suspect information and have little to go on.
