FORT COLLINS, Colo. (AP) — Authorities say two more people have reported their windows being shattered while driving in northern Colorado, adding to several similar incidents over the past week.

The Coloradoan reports deputies with the Larimer County Sheriff's Office went to an insurance firm in Fort Collins on Wednesday after a woman reported her rear passenger truck window had shattered while she was driving on Interstate 25. Also Wednesday, another driver reported her passenger side window shattered while she was driving on a frontage road south of Windsor.

Investigators have not determined if the series of shattered windows are linked or whether they are tied to the shooting of a woman who was driving on I-25 last Wednesday.

At least seven people have reported their windows being shattered in northern Colorado since April 21, including the woman who was shot.
