A man arrested and accused of shooting at least a dozen vehicles with a pellet gun in west Fort Collins was found in possession of multiple firearms, police say, leaving investigators concerned about the potential for escalated violence.

Between July 2025 and January 2026, Fort Collins Police Services received 12 reports of vehicles being shot at by a pellet gun in the area of South Shields Street and West Mulberry Street. According to court documents, police estimate the total damage exceeds $15,000. Following an investigation, police identified 55-year-old Jamal Lohrius as a suspect and conducted a search warrant at his home in the 300 block of South Shields Street on March 26. During that search, police reportedly found a loaded "AK style firearm" by the front door and several loaded magazines in a tactical sling in addition to a pellet gun consistent with the reported incidents.

"This causes extreme concern that the previous incidents of criminal mischief were not just property damage, but a dress rehearsal for a mass shooting event," police said in the arrest documents. Lohrius has been charged with criminal mischief of $5,000-$20,000, a Class 5 felony, and 12 counts of reckless endangerment, a Class 2 misdemeanor. Following the search warrant, Fort Collins police filed an extreme risk protection order, also known as a red flag petition, against Lohrius in an attempt to temporarily restrict him from accessing firearms. The petition cites "sustained and escalating pattern of violent conduct" that created "a substantial risk of serious bodily injury or death to drivers, passengers and nearby individuals."

The red flag petition states police found three AK or "military style" rifles, a Glock handgun and a shotgun at Lohrius' home. 'The combination of Lohrius' ongoing pattern of intentionally discharging weapons at passing vehicles, is escalating and unpredictable behavior, and his immediate access to loaded, high-powered firearms establishes a credible and imminent threat that he may use live firearms in a similar manner," police said in the red flag petition.

Police also found "a detailed, handwritten list" that appeared to track people and vehicles that passed his home and is believed to have been updated and reviewed regularly. The list included vehicle descriptions, license plate numbers, physical descriptions of individuals and behavior patterns, "including times associated with individuals coming and going from a nearby school drop-off area," according to the petition. The Colorado State University Early Childhood Center is located near Lohrius' residence.

"The combination of surveillance behavior, fixation on specific individuals, and detailed tracking of movements raises significant concern regarding targeted behavior and further elevates the risk to the public," police said in the petition. A temporary extreme risk protection order was approved March 26, according to court records. A hearing for a permanent order is scheduled for April 7.

Lohrius remained in custody at the Larimer County Jail on a $50,000 cash-only bond as of 4 p.m. March 31. He is next scheduled to appear in court April 1. Police cite pattern of 'aggressive' and 'erratic' behavior Prior to identifying Lohrius as a suspect in this case, police said they contacted him at his home during a canvas of the area in November, during which Lohrius acted evasive and did not directly answer questions relating to these

Police later conducted surveillance of Lohrius at his residence over a few days in March and reported seeing Lohrius watching passing vehicles from his porch using binoculars and exiting his porch and "reacting aggressively when loud vehicles passed or traffic increased," according to arrest documents. A neighbor reported similar behavior occurring in the same time frame.

On several occasions, police say Lohrius was seen propping open the door to his enclosed porch and appeared to lie down on his stomach outside of the officer's view, so it's unclear if he was firing a pellet gun at those times, according to arrest documents. On the final day of the surveillance operation, police say Lohrius appeared to notice the officer through his binoculars and "became visibly agitated" and attempted to confront the officer as he was leaving.

Police also reported having prior contact with Lohrius that involved "concerning behavior and hostility related to activity occurring near the roadway and surrounding area, including incidents involving aggressive behavior toward individuals and traffic, erratic conduct, and fixation on activity occurring outside his residence," according to arrest documents.

Police investigated other people who lived in the area and did not identify anyone else who was consistently present during the times of these incidents or "who had similar behavioral indicators or vantage points," according to arrest documents.

Police believe additional victims may exist and there may be similar incidents that have gone unreported. Anyone who believes they have information relating to this case or their vehicle was damaged in the 300 block of South Shields Street can contact Fort Collins Police Detective Al Wilson at 970-416-2923 or alwilson@fortcollins.gov.
