A 23-year-old man faces allegations of first-degree murder in a road rage incident in which he allegedly shot four people. Those shots killed a boy, critically injured his mother and brother, and wounded a bystander in a Westminster shopping center parking lot.

Jeremy Webster of Colorado Springs was officially booked into the Adams County Jail at 1:39 a.m., more than 10 hours after the shooting, said Cheri Spottke, Westminster police spokeswoman.

Westminster detectives interviewed the man for several hours after he was arrested without incident on Interstate 25 in Castle Rock. Through those interviews police determined he did not have a relationship with any of the people who were shot.

According to a search warrant for Webster’s car that was obtained by Denver7, one of the woman’s three sons told police his mother and Webster had some sort of altercation near the intersection of Sheridan Boulevard and Turnpike Drive.

The warrant says Webster then followed the 41-year-old woman and her children to the office complex at 5150 80th Avenue and parked behind them. The woman’s 12-year-old son told police that his mother took a photo of Webster’s license plate before she got out of the car.

Witnesses said Webster and the woman argued as she and her children got out of the car. Webster then allegedly shot the woman multiple times, according to the warrant. He then turned and allegedly shot at two of the woman’s sons. The 12-year-old was able to run away, but the 13-year-old boy and 8-year-old boy were shot multiple times, according to the warrant. The 13-year-old boy died.

After shooting the woman and two of her children, Webster then allegedly made eye contact with a man in a pickup truck and fired multiple shots, hitting the man in both arms, the warrant says. The man was able to drive out of the parking lot and his 12-year-old daughter was not injured.

Webster has been arrested for investigation of first-degree murder, first-degree murder extreme indifference and three counts of first-degree assault, according to Colorado Bureau of Investigation records. Webster does not have a criminal record in Colorado.

Spottke said police are conducting photo lineups using the suspect and are asking the public not to share his picture. About 20 people witnessed the shooting and police are not releasing the suspect’s photograph until that part of the investigation is complete.

The names of the victims have not been released.

Police allege Webster climbed back in his car after the shooting and and drove onto Interstate 25 and headed south.

Patrons at the shopping center, who witnessed the shooting, described hearing multiple gunshots in an area heavily saturated with bars, retail stores and two dentists’ offices.

Just saw a scene that brought me to tears. Brandy Navarette lives near the shooting. His 6-y/o granddaughter Lilly Diaz wanted to bring flowers for the little boy that died, she said. They brought flowers, a rosary & prayed in the parking lot. She asked me why he had to die. pic.twitter.com/glE2VoFSIt — Elizabeth Hernandez (@ehernandez) June 15, 2018

The parking lot was quiet Friday morning.

Brandy Navarette, who lives nearby, came to the lot with his 6-year-old granddaughter Lilly Diaz who wanted to bring flowers for the boy who was killed Thursday.

The pair also brought a rosary and prayed in the parking lot.
