LOVELAND, Colo. -- It has been more than a year since three sets of random shootings put people on alert in communities in Larimer County, as well as up and down the Front Range. And now there are new developments.

Two people were killed in the street, a third was hurt when she was shot in the neck while driving on Interstate 25. All happened at different times in different places, but all appear to be related.

On Tuesday, the Northern Colorado Shooting Task Force released surveillance video of a pickup truck investigators believe was used in a June 2015 shooting.

Someone fired a shotgun from the vehicle and killed a 66-year-old man while he walked down the street.

Task force leaders said the group has investigated thousands of tips, interviewed 1,000 people and checked nearly 2,000 vehicles.

No arrests have been made in the six shootings.
