St. Paul police have a better idea of what kind of vehicle was involved in a fatal hit-and-run last week, according to an announcement on Friday.

Therese Klotz, 53, of St. Paul, was hit by a vehicle about 6:40 p.m. Nov. 1 as she was getting out of her car in front of a friend's house on the 700 block of Randolph Avenue. She died at Regions Hospital.

Klotz's friend, who was also outside at the time of the accident, said the vehicle continued up the street and turned left onto 7th Street, heading toward downtown.

Investigators found a ­silver right mirror cover at the scene. Police said Friday that the cover came from a 2001 to 2006 Lexus LS 430 sedan, but police also are interested in locating sports-utility ­vehicles that match the description since Klotz was originally reported to have been hit by a SUV.

As of Friday afternoon, there haven't been any arrests. Anyone with information is asked to call police at 651-266-5582.

Last week's hit-and-run is one of several in the city within the last few months.

On Sept. 13, 92-year-old Roy Kromschroeder was riding his motorcycle to the mall for his daily walk when he was struck and killed by a hit-and-run driver at Prosperity and Ivy avenues. A 26-year-old woman has been charged in his death.

On Oct. 3, Wade Souster, 31, was found unconscious at Phalen Boulevard and Atlantic Street after being struck by a hit-and-run driver. He is being treated for brain injuries, pelvic and facial fractures, bruised lungs and a broken leg. Police are still looking for suspects.

In another incident, a 32-year-old man was discovered on Oct. 13 about 7 a.m. on the grass near a home in the 100 block of Larpenteur Avenue E. It's not yet clear whether he was hit by a vehicle or was attacked and then dumped at the location. The man suffered spinal injuries. There haven't been any arrests in the case.
