DEARBORN (AP) — A 14-year-old Detroit boy wearing a GPS tether is one of three teens arrested in the armed robbery and fatal shooting of a 29-year-old woman.

The 14-year-old, a 13-year-old and 17-year-old are being held in connection with last week’s killing of Saja Aljanabi and they could be involved in other crimes in the area, Dearborn Police Chief Ronald Haddad said Thursday.

Aljanabi was shot while sitting in a car. Haddad said that around the same time, another woman was robbed in Dearborn and a shot was fired at a man in separate incidents.

The 17-year-old was arrested Saturday following a traffic stop and crash on Detroit’s west side.

The 13- and 14-year-olds were arrested Monday in Detroit. The younger two suspects are being held in the county youth home, while the 17-year-old is jailed.

The names of the suspects were not released. Dearborn officers had made previous contact with the 13- and 14-year-olds in a shoplifting case that led to the 14-year-old wearing a tether, Haddad said. The tether did not factor into their arrests in Aljanabi’s slaying, he added.
