SUPERIOR TOWNSHIP, Mich. -- A Superior Township couple and their 8-year-old son were killed this weekend in a crash involving a Volvo and a 1929 Duesenberg.

Bradley Miles Patton, 35, took his family for a ride in the classic automobile when the vehicle was struck broadside by the driver of a Volvo who ran a stop sign at the intersection of Ford Road and Old Ford Road in Superior Township, according to the Washtenaw County Sheriff's Department.

Police said all five occupants of the Duesenberg were ejected from the car and were lying in the roadway when authorities arrived at the scene.

Patton, his wife, Kristin, 35, and their son, Nathan, suffered fatal injuries in the crash. The couple's two daughters, Emily, 7, and Taylor, 9, were taken to the University of Michigan Hospital, where they remain in stable condition.

An investigation revealed that the family in the Duesenberg was headed eastbound on Ford Road when the driver of the Volvo ran a stop sign while turning onto southbound Old Ford Road from westbound Ford Road, according to the sheriff's department. The impact caused the classic car to roll and the family was ejected from the vehicle.

The Duesenberg was owned by a Bloomfield Hills resident and had just recently been restored. There was no word on how much damage was done to the car, which is valued at over $500,000.

The driver of the Volvo, a 25-year-old Ann Arbor resident, was not injured in the crash. He was arrested and taken to the Washtenaw County Jail, but was later released pending the authorization of charges by the prosecutor's office, which are expected to come later this week, according to the sheriff's department.

Bradley Patton was a six-year veteran of the Ypsilanti Fire Department. Flags were being flown at half-staff outside the station and a black band covered firefighters' badges in memory of Patton.

"It's devastating," said Capt. William Wagner, of the Ypsilanti Fire Department. "It's probably my toughest day being on duty here at the fire station in my 17 years."

A funeral date for the couple and their son had not yet been set, but a memorial fund has been established for the family.
