FENTON, Mo. – St. Louis County Police have released details of their investigation into the fatal shooting of a former doctor, which occurred at his estranged wife’s home in Fenton, Missouri, on March 21.

The incident unfolded when police responded to a harassment call at the residence on Hawkins Bend Drive just after 10 a.m. Officers encountered Lanis and attempted to coax him outside to place him under arrest.

Video footage from the scene shows officers at the door for about two minutes, repeatedly asking 38-year-old Aleksandr Lanis to come outside.

According to reports, Lanis requested twice to be given a minute before police entered the home to attempt an arrest.

Lanis died at the scene, but details surrounding how the shooting occurred remain unclear.

The Smith family, in-laws of Lanis, released a statement regarding the shooting, saying:

“We were deeply saddened by the choices Aleksandr made in his final moments, and we are grateful to the officers who gave him every opportunity to choose a different outcome.”

The investigation continues as authorities seek to clarify the circumstances leading to the shooting.
