DODGE CENTER, Minn. -- Investigators say the driver of a Hummer was putting away his cellphone when he rear-ended a car in Dodge County earlier this month, killing a woman and her daughter, according to a Rochester Post Bulletin report.

Tanner Kruckeberg, 24, of Dodge Center allegedly told the Minnesota State Patrol that “he was looking down at his center console area to put away his cellular phone” when he crashed into the back of a Mercury Milan, the Post Bulletin report said.

The driver of the Milan, 43-year-old Rachel Marie Harberts, and her 8-year-old daughter, Emerson, were both killed; Harberts’ 12-year-old son, Jaxon, was injured but is recovering, according to the family’s CaringBridge page.

The State Patrol obtained a warrant to search the Hummer’s sensing and diagnostic module, airbag control module and any other event data recording devices, the Post Bulletin report said.

Alcohol was not a factor in the crash, the State Patrol said.
