A mother of three who married her high school sweetheart was identified Monday as the driver who was killed in a weekend collision in Inver Grove Heights with a motorist who is jailed on suspicion of being drunk and having no driver’s license.

The crash Saturday afternoon at the residential intersection of Dawn Avenue and 70th Street killed Kim M. Caswell, 42, of Roseville, according to the Hennepin County medical examiner’s office.

Caswell had just finished her rounds in her new duties as a HealthEast home health care nurse and was heading home at the time of the crash, her mother-in-law said Monday.

Nicholas Anthony Indehar, 21, of Inver Grove Heights remains jailed and accused of criminal vehicular homicide, drunken driving, careless and reckless driving, running a stop sign and driving with a revoked driver’s license. A spokeswoman with the county attorney’s office said charges were expected Tuesday.

Indehar’s record in Minnesota since August 2011 includes two convictions for drunken driving, two for speeding and one for illicit drug possession. He has not had a valid license since March 2013, according to the state Department of Public Safety.

Arriving officers found Caswell’s minivan crashed against a utility pole on the northwest side of the intersection with live electrical wires draped over it, police said. Indehar’s car was nearby.

Indehar was helped out of his car by bystanders, treated for minor injuries at Regions Hospital in St. Paul and then jailed, police added.

Police Lt. Joshua Otis said Monday that Indehar “had an odor of alcohol” at the scene and there was “some self-admission to our officers” about having been drinking.

Caswell was heading west on 70th in her van and was hit broadside by Indehar’s car, Otis said. There were no traffic controls for Caswell to observe, when Indehar went through a stop sign at what “we believe” was a high rate of speed, Otis added.

Jon and Kim Caswell dated while both attended Mounds View High School and were married for 15 years, said mother-in-law Carole Caswell.

“She was a quiet person who was very much into the kids,” girls ages 15 and 13, and a 10-year-old son, Carole Caswell said. “She hauled them all over to their sports. She was just an all-around mom.”

Kim Caswell’s older sister, Becky, said “there’s been a lot of tears all weekend,” but the family is now focused on the couple’s “wonderful, strong kids. Helping them is what it’s all about.”

Caswell worked as a registered nurse in the emergency room at Woodwinds Hospital in Woodbury until September, when she was transferred to home health care duties, a spokeswoman for HealthEast said.
