The vehicle that struck and killed a St. Louis Park man as he rode his bike to work earlier this month was a tannish gold/light brown Jeep Grand Cherokee that was built in 1996, 1997 or 1998, Minneapolis police said at a news conference today.

Police are asking the public's help in locating the driver and the vehicle, which fled after striking Jimmy Nisser, 64, as he rode to the Minikahda Club at about 4:20 a.m. on Sept. 11.

Police released detail about the vehicle today after paint chips and debris from the scene were analyzed by the Bureau of Criminal Apprehension. They also said that the vehicle has front-end damage.

Police held the news conference near a memorial that stands along Excelsior Blvd. where Nisser was struck. The memorial is a white bike with a photo of Nisser and his eulogy taped to it. The bike is surrounded by flowers.

In an unrelated case, police still have made no arrests in a case in which a bicyclist was struck and injured last Wednesday on Lyndale Avenue near Linden Avenue in north Minneapolis.

Rodney Scroggins, 54, of Minneapolis, was riding his bike to work when he was struck around 2 a.m. He suffered a dislocated shoulder, broken bones and other injuries.

Scroggins was in critical condition Monday morning at Hennepin County Medical Center in downtown Minneapolis, a hospital spokeswoman said.

Anyone with information about either case is asked to call Sgt. Bruce Folkens at 612-673-3410 or Sgt. Chris Karakostas at 612-673-3400.
