A Longmont man was shot and killed by Boulder County sheriff's deputies and Longmont police officers following a chase early Monday.At 2:46 a.m. a deputy performed a traffic stop near 8th Avenue and Lashley Street and noticed the driver had a weapon, according to Longmont Public Safety Chief Mike Butler.The driver took off from the stop, leading deputies on a 20- minute chase throughout the city, throwing things out the car window."My assumption is he was pitching evidence, things he didn't want to be caught with," Boulder County Sheriff Joe Pelle said.Officers made multiple attempts to deploy stop sticks in front of the fleeing vehicle without success.A Longmont officer performed a maneuver to stop the suspect vehicle near the intersection of 3rd Avenue and Emery Street."One of the deputies fired a less-then-lethal round at the suspect," said Butler. The shot, from a bean-bag gun, broke the driver's side window of the car.That is when the man brandished a weapon and was shot and killed, according to police. He was identified Monday as Brian Chistopher Naranjo, 35. Neighbors reported hearing five or six shots."I didn't hear much over the sirens, but I did hear gun fire," said Tabitha Silvestri, who's apartment is along 3rd Ave. "I went and got my child. Her bedroom faces 3rd Ave. I woke her up and we got down on the floor," she said.No one else was injured in the shooting.Police are not releasing the driver's name. He was wanted on misdemeanor warrants.East Third Avenue, between Main St. and Collyer St. were shut down for the duration of the on-scene investigation.Boulder Countys multi-agency Critical Incident Investigation Team is in charge of the investigation, which is expected to take a couple of weeks to complete. The names of the officers involved have not been released."They have a tough road ahead. This is tramatic for those deputies and police officers. No one wants to take a life or be involved in a shooting," said Pelle.
