Former Mercy Physician Fatally Shot by St. Louis County Police During Warrant Service in Fenton
Fenton, MO – A former physician at Mercy Health was shot and killed by St. Louis County police officers on Friday morning after an attempted arrest escalated into a fatal confrontation.
The deceased, identified as 38-year-old Aleksandr Lanis, was the subject of an arrest warrant for first-degree harassment.
Officers arrived at approximately 10 a.m. at a residence in the 1000 block of Hawkins Bend Drive to serve the warrant when the situation turned violent.
According to police, officers made contact with Lanis at the door of the home, where a verbal exchange ensued.
The encounter quickly escalated into a physical struggle when Lanis allegedly brandished a firearm.
In response, both officers discharged their weapons, striking and fatally wounding him. A firearm was recovered at the scene.
One of the officers sustained a non-gunfire-related hand injury during the altercation but was treated at the scene and did not require hospitalization.
The officers involved in the shooting have been identified as a 30-year-old with seven years of service and a 22-year-old who has been with the department for one year.
Neighbors in the area expressed shock following the incident. “We heard about 15 shots,” one resident recalled. “I didn’t even know he had weapons. He mostly kept to himself.”
Authorities confirmed that Lanis shared the home with a woman who was in the process of divorcing him.
She and their young child were not present at the time of the shooting.
Mercy Health acknowledged that Lanis had previously been employed as a physician but declined to disclose the timeframe of his tenure with the organization.
The investigation into the officer-involved shooting is ongoing.
City of Hammond, Louisiana — At approximately 11:50 p.m. on February 24, 2026, officers with the Hammond Police Department responded to a report of shots fired involving one possible victim.
Upon arrival, officers located a 14-year-old juvenile female, identified as Tyronai Reed, suffering from an apparent gunshot wound.
Emergency medical assistance was rendered at the scene, and she was transported to North Oaks Health System for treatment.
Despite life-saving efforts, Reed later succumbed to her injuries.
