A man is suspected of killing two people, including a person he was in a prior relationship with, and then gunning down four more at another home hundreds of miles away in connected homicides, authorities in Florida said.

Law enforcement in Fort Lauderdale and Sarasota County on Wednesday both identified 51-year-old Russell Kot as a suspect in the homicides. He died of apparent self-inflicted wounds on Tuesday following his alleged killing spree, authorities said.

Deputies in Sarasota County initially responded midday Tuesday to a shooting at a residence in a gated community, authorities said.

Four people were killed — including a man who was shot while approaching the front door, according to the Sarasota County Sheriff’s Office. Two women and another man were found dead inside the home, located in the Amberlea neighborhood, authorities said.

The suspect, Kot, was also found dead in the home, the Sarasota County Sheriff’s Office said. Video showed his vehicle entering the neighborhood at around 11 a.m. Tuesday, it said. Shortly after, a neighbor’s Ring camera captured the sound of gunfire, the sheriff’s office said.

The man who was shot outside the residence was seen entering the neighborhood in his vehicle about 37 minutes later, the sheriff’s office said. Responding deputies found neighbors performing CPR on him in the front yard, it said.

Later Tuesday afternoon, over 200 miles away on Florida’s east coast, police conducting a well-being check at a residence in the Victoria Park section of Fort Lauderdale found two people dead inside a residence, police said.

While authorities in Sarasota County were working to identify the victims and suspect in their case, the sheriff’s department said Fort Lauderdale police contacted them to advise that they believed the double homicide and Sarasota County shooting might be related. 

Following the Fort Lauderdale homicide, the suspect’s vehicle was captured on camera traveling near Sarasota, before the quadruple homicide in Amberlea, authorities said.  

Kot lived in Fort Lauderdale and had a “previous romantic relationship” with one of the Fort Lauderdale victims, according to the Sarasota County Sheriff’s Office. That victim was connected to the Sarasota County victims, officials said, though they did not elaborate.

Police on Wednesday identified the victims in Fort Lauderdale as Larisa Blyudaya, 46, and Ben Azivov, 18.

The victims in Sarasota County were identified by the sheriff’s office on Wednesday as Olga Greinert, 49; Florita Stolyar, 66; Anatoly Ioffe, 61; and Yaroslav Blyudoy, 39.

The homicides remain under investigation. 

A motive in the Sarasota County incident is unknown at this time, the sheriff’s office said Wednesday.

“Based on our preliminary investigation, it appears that the suspect died of self-inflicted wounds, and there are no known documented mental health crises nor history of violence associated with him,” the Sarasota County Sheriff’s Office said.
