Police say a man shot and killed three people before opening fire on officers Saturday morning.

It began with a shots fired call at around 8:45 a.m. in the 200 block of Prospect Street just east of downtown, police said. Police say one person died at that location.

Witnesses said the suspect lit the second floor of a home on that street on fire.

The exact timeline of events after that has not been confirmed by investigators, but we know that a bicyclist was found shot to death on Prospect Street. Two women were also shot, apparently by the same man, in the area of E. Platte Ave. and El Paso St.

Police later found the suspect near Platte Avenue and Wahsatch Avenue. That is where police said he opened fire on officers. Police shot back, killing him.

Ross Trottier was caught between the suspect and officers, he says he'd be dead right now if he hadn't made a quick decision to lie on the ground. "The cop pulled up and said drop your gun and as soon as I heard that I got on my stomach in the median and they started shooting at each other and the bullets went over me," Trottier said.

Raw: Springs shooting witness caught in the crossfire

The El Paso County Sheriff's Office is now leading the investigation into the officer-involved shooting.

Deputies said the suspect had multiple weapons on him. An early investigation shows possibly four Colorado Springs police officers fired at the suspect.

Authorities said the following roads are closed:

Wahsatch Ave. and Platte Avenue were closed for most of the day. They reopened at around 5:15 p.m.

El Paso County Sheriff's deputies ask you to call 719-390-5555 if you live in the area and sustained damage to your home or vehicle.
