Missing marijuana early Monday started an altercation and then a three-car chase that ended with an 18-year-old Caseyville woman being ejected from a car and killed, police said.

The car's driver, Donald Joseph Friese, 28, fled after the crash and was being sought Monday, police said. His city of residence was unavailable.

Mercedes Ferrarie-Troisi, 18, was identified as the victim by St. Clair County Coroner Rick Stone. She was pronounced dead at 8:55 a.m. Monday as the result of internal injuries.

"Apparently there was a chase going on and a two vehicle collision that resulted in a double roll-over. Ferrarie-Troisi was ejected from the vehicle," Stone said.

Fairmont City Police Chief Scott Penny described the accident as "tragic." Ferrarie-Troisi was thrown from the vehicle when it crashed in the 4900 block of Collinsville Road, then one of the pursuing vehicles landed atop her.

"Tremendous damage was done to both of the vehicles that were involved because of the high rate of speed they were traveling at," he said.

Penny said there was an altercation over some missing marijuana at a house in the 8500 block of Collinsville Road, which is the unincorporated State Park Place neighborhood near Collinsville.

"After the disturbance, three vehicles began pursuing each other on Collinsville Road to the parking lot of the Rural King in Collinsville," Penny said.

There a scuffle took place. A green Buick sedan with the victim and a male driver fled and was pursued by a black Denali and a white Chevrolet, a total of eight people all headed west on Collinsville Road, Penny said.

"The drivers were traveling at speeds in excess of 100 miles per hour and the drivers lost control, resulting in both vehicles rolling over," Penny said of the sedan and Denali. The vehicles at 4:45 a.m. Monday landed in a ditch.

The accident closed Collinsville Road in both directions for the morning.
