PHOENIX — The Latest on a fatal shooting on Phoenix freeway (all times local):

11:50 a.m.

Phoenix police say the fact that a woman fatally shot while driving on a Phoenix freeway reported during a 911 call that she had been followed before getting on the freeway system lowers the likelihood that the killing was random traffic violence.

Police additionally say the circumstances also increase the likelihood that the Wednesday evening killing of 49-year-old Dinya Farmer on State Route 51 may be related to something else that hasn’t yet been determined.

Police previously said there were five or six 911 calls about a white truck driving aggressively on Interstate 10 and that the shooting victim was one of the callers and that she reported being chased by the truck.

It is described as having a ladder rack and tool box. Its occupants are described only as Hispanic males.

Sgt. Jonathan Howard says there’s no indication the incident is related to either a 2015 series of shootings on Phoenix freeways or a 2016 series of shootings largely on or near residential streets.

8:45 a.m.

Police say a woman fatally shot while driving on a Phoenix freeway Wednesday night said during a 911 call that a white work truck began following her on a local street several miles from where she first entered the freeway system.

Sgt. Jonathan Howard says police hope somebody in the area of South Seventh Avenue and West Broadway Road can provide information about the suspect vehicle that was reportedly carrying three people.

The truck is described as having a ladder rack and tool box. Its occupants are only described as Hispanic males.

Howard says the woman’s vehicle crashed on the State Route 51 in central Phoenix after a 911 operator heard shots fired. The woman previously was on Interstate 10 before she got into the SR 51.

6 a.m.

Phoenix police say a woman was fatally shot while driving on a freeway and calling 911 to report that she was being chased by three people in a truck.

Sgt. Jonathan Howard says the woman’s car crashed on the median of the State Route 51 freeway after a 911 operator heard shots fired during the call Wednesday night.

Police are looking for a white work truck with ladder racks and a tool box. Those inside the truck were described only as Hispanic males.

Howard says the incident began with five or six 911 calls about a white truck being driven aggressively on westbound Interstate 10.

Howard says the woman who was killed said the truck was following her as she went from I-10 to the SR 51 in central Phoenix.
