The driver accused of running a stop sign north of the Twin Cities and killing another motorist has a long history of traffic violations that includes driving on a suspended license, many instances of speeding and disregarding a stop sign, according to state court records. 

Heidi L. Butau, 44, was identified Thursday as the driver who struck John C. Ploetz, 75, of Harris, Minn., about 5 miles northeast of Cambridge on Sunday.

Butau, of Cambridge, has been convicted in Minnesota eight times for speeding, twice for driving with a suspended license, twice for having expired vehicle tabs, once for running a stop sign and once for texting while driving. On the day of the crash, her license was valid, the state Department of Public Safety said Thursday.

Chisago County Sheriff’s Capt. Keith Hoppe said his office continues to investigate the case, which will be sent to the county attorney’s office for possible charges. The crash left Butau with minor injuries.

Ploetz, along with his wife, owned and operated Lofgren Trucking in nearby Rush City for 30 years until 2005.
