Police in the US state of Arizona say a single suspect may be responsible for a series of shootings that have left seven people dead.
The first attacks were reported in March when two men were shot while walking outside; both survived.
The last incident was reported on 12 June when three women were shot and killed outside a home in west Phoenix.
All of the shootings occurred at night, and the victims appear to have been targeted at random.
A witness to one of the shootings helped detectives develop a sketch of the suspect.
“Someone out there knows who did this,” Phoenix Police Chief Joseph Yahner said. “We need our community to help us solve these cases.”
