The man arrested in connection with a deadly parking lot brawl has a history of alcohol-related violence, according to court records.
Jonathan L. Sosnowicz, 31, was arrested Sunday on suspicion of second-degree murder and three counts of aggravated assault after the driver of a Hummer ran down a 25-year-old man in the parking lot of Salty Senorita, 1862 S. Stapley Drive.
Sosnowicz was convicted in 2004 on a count of assaulting a police officer.
Court records state that he was kicked out of Axis-Radius Nightclub in Scottsdale on March 20, 2004, and then in the parking lot began beating up a friend who refused to let him drive drunk.
Later that night on the way to jail, Sosnowicz kicked a sheriff’s deputy and then kicked a window out of the patrol car and tried to climb out of the vehicle as it traveled 70 mph on the highway.
Sosnowicz was given three years probation, but he violated the probation twice with drunken arrests and eventually was sentenced to a year in prison.
He was also convicted of disorderly conduct in Scottsdale Municipal Court in 2003.
Mesa police say that at 2:12 a.m. Sunday, Jeremy Privett, 25, got into a fight with Sosnowicz .
Privett is the stepson of a retired Mesa police commander, Ron Kirby.
According to Mesa police, witnesses said the man who fought Privett got into a white Hummer and left, but returned five minutes later, flashed the headlights and drove straight at a group of four.
One person was grazed, the other two got out of the way and Privett was struck.
A Gilbert police officer saw the Hummer pull into a garage at 774 W. Sereno in Gilbert.
Sosnowicz called Gilbert police at 4 a.m. to report that he and his roommate had been in a fight somewhere.
The roommate, Jason Jordan, told police he jumped into the back of the Hummer at the Salty Senorita and felt a bump as Sosnowicz drove away fast.
Police found red stains and fibers on the grill of the Hummer.
