FBI officials have doubled a reward — to $20,000 — for information leading to the arrest, prosecution and conviction of the person or people responsible in three recent shootings in Northern Colorado.

Officials also announced that a single telephone number and email address has been established to contact the Northern Colorado interagency task force in charge of investigating the shootings, two of which were fatal.

“The tip line is a Sheriff’s Office phone number, but it’s all routed to the task force,” David Moore, task force spokesman, said. “It’s all going to go to a phone bank, where the information will be pulled out of there and dealt with appropriately.”

Information on who is answering tip line phone calls was unavailable.

The task force is a collaboration of the Windsor Police Department, Federal Bureau of Investigation, Larimer County Sheriff’s Office, Larimer County District Attorney’s Office, Weld County Sheriff’s Office, Weld County District Attorney’s Office and, most recently, Loveland Police Department.

Moore, who released the statement Tuesday afternoon, also indicated task force investigators are interested in speaking with people who may have witnessed the crimes.

Specifically, officers are interested in speaking with the person who was driving a white Ford SUV on May 18 near Weld County Road 72 and Weld County Road 15 in Windsor — where a bicyclist was shot and killed in the morning.

The release also noted that investigators would like to talk to anyone who was near the area of East First Street and St. Louis Avenue in Loveland last Wednesday night between 10 and 11 p.m. — the location and time of the most recent fatal shooting.

This most recent shooting has not officially been connected to the previous two shootings, which police have confirmed are related.

Moore said he did not know where officers received information about the white SUV but suspects someone in the area at the time has informed investigators of the vehicle.

“The main thing is they could have seen the incident,” Moore said. “Ultimately if investigators can talk to [the driver] they can rule [the driver] out as someone they need to speak to.”

Moore said on Monday that there is no timeline as to when new information in the cases will be available.

Mark Rudolph, Loveland Police Department’s crime analyst, said since Jan. 1, 2006, excluding last week’s shooting, Loveland has had five fatal shootings that were not suicides — all of which have been solved, and none was a random shooting.

Capt. Robert Coleman, the task force’s commander, has assigned a unit within the investigating team to continue to respond to incoming reports of shattered vehicle windows in the area.

These shattered window incidents and the three shootings have not officially been connected.

Anyone with information regarding any of these cases is asked to call the task force’s tip line at 498-5595, callers will remain anonymous. They may also send an email to taskforce@larimer.org.
