A Pipersville man basically was playing Russian roulette when he drove his Ford Mustang Cobra at more than 140 m.p.h. into another car on Thanksgiving Eve, killing a 9-year-old Bucks County girl and critically injuring her grandmother, authorities said Thursday.

"If someone's unfortunate to be in your path, they're done," Bucks County District Attorney David Heckler said after announcing the arrest of Drew Bodden, 37, on third-degree murder and other charges.

Driving at 142 to 154 m.p.h., "you've completely given up control of what happens," Heckler said.

Bodden's souped-up 2003 Mustang may have been playing a "cat-and-mouse game" with a black Cadillac seconds before the crash on the busy Route 611 Bypass in Doylestown Township about 6:35 p.m., Assistant District Attorney Robert James said.

There were "no facts to indicate drag racing," James said. "Maybe on Bodden's part."

Bodden and his attorney declined to comment after the lifelong Bucks resident was released on $500,000 unsecured bond.

Killed in the crash was Holly Huynh, who was buckled into the backseat of her grandmother's 2008 Honda CR-V. She suffered a broken neck and other injuries and was declared dead at the scene, according to the affidavit. The girl would have been 10 next Tuesday.

Her grandmother, Suzanne Berry, 55, remains on a respirator at Temple University Hospital with a severe brain-stem injury, James said.

Bodden and his girlfriend, Christine Mokrynchuk, 43, also were seriously hurt. Bodden suffered a broken arm and leg and was released from the hospital Tuesday. Mokrynchuk suffered a broken ankle, wrist, and sternum and a possible head injury, James said.

That night, Berry was driving Huynh to their Pipersville home from the girl's gymnastics class, while Bodden and Mokrynchuk were heading home from dinner, according to the affidavit.

Bodden was driving the Mustang in the left northbound lane when the Cadillac, traveling 75 to 80 m.p.h., moved over to let it pass, James said.

Within one-eighth of a mile, the Mustang rear-ended the Honda, crushing both cars and damaging the Cadillac as it drove through the wreckage, James said.

Investigators determined the Mustang was traveling 142 to 154 m.p.h., while the Honda was traveling 60 to 70. The speed limit for the four-lane bypass is 55.

The murder charge carries a possible 40-year sentence and $50,000 fine.
