FORT COLLINS, Colo. (CBS4)– The FBI has doubled the reward for information in three shootings in Northern Colorado that have left two people dead. A special task force has been assembled to investigate the cases and take tips from the public, and the driver of a Ford SUV may have information on one of the shootings.

Authorities would like anyone with any information to call the Task Force Tip Line at 970.498.5595 or via email.

The task force is comprised of individuals from several police departments and sheriff’s offices in northern Colorado, investigating any possible link between the slaying of a man on a neighborhood sidewalk and two previous shootings of a bicyclist and a driver.

Investigators said although there is no definitive link between Loveland shooting and the other two cases, enough similarities are present to warrant investigating the potential of a link existing.

The FBI has doubled its initial $10,000 reward to $20,000 for information on the unsolved cases that authorities say are related — though they haven’t said how. Police and the FBI have refused to comment on the possibility of a serial shooter.

The reward being offered by the FBI is for information leading to the arrest, prosecution and conviction of the individual or individuals responsible for those crimes.

In the latest case, 65-year-old William Connole was found on a sidewalk along a main street in Loveland.

The task force is interested in talking to anyone who was near the area of E. 1st Street and St. Louis Avenue in Loveland between 10 p.m. and 11 p.m. on June 3, the night Connole was killed. The task force said that includes vehicular, bicycle and pedestrian traffic in that area.

The bicyclist, 48-year-old John Jacoby, was found dead May 18 along a rural road in Windsor.

The task force is interested in speaking with an individual who was driving a white Ford SUV on May 18 near Weld County Road 72 and Weld County Road 15, the morning Jacoby was killed. The task force believes this person may had important witness information for that homicide investigation in Windsor.

On April 22, Cori Romero, 21, was driving on Interstate 25 when she was shot in the neck. She survived. All three shootings occurred within 15 miles of each other.

Task Force Commander Capt. Robert Coleman has assigned a unit of the task force to continue investigating all reports of shattered vehicle windows in the area. There is no evidence that links the reports to the three shootings being investigated by the task force.
