ATF Offers $10,000 Reward for Double-Homicide, Arson Suspect

SUMNER, Wis. — The Bureau of Alcohol, Tobacco, Firearms and Explosives is offering a reward of up to $10,000 for information that leads to the apprehension and conviction of a Fort Atkinson, Wisconsin, man believed to be responsible for two intentional homicides, an attempted homicide and an arson in Sumner last month.

According to Jefferson County court documents, the suspect, Kevin P. Anderson, 62, is wanted in connection with the killing of his biological sister and her husband, shooting at a Jefferson County Sheriff’s deputy and for setting his deceased parent’s Sumner house on fire on June 16. Investigators were unable to locate Anderson after the incident.

In addition to ATF’s potential $10,000 reward for information, the U.S. Marshals are working closely with case investigators to help apprehend Anderson. Anyone with information on his whereabouts is asked to contact the Jefferson County Sheriff’s Office at (920) 674-7311.

Information can be submitted anonymously, but if a reward is sought, be sure to include contact information. Information eligible for reward must lead to the arrest and conviction of this individual.

ATF is working in partnership with the Jefferson Sheriff’s Office, Wisconsin Department of Justice – Division of Criminal Investigation, and the U.S. Marshal Service.

ATF’s mission is to safeguard the public from violent crimes involving firearms, explosives, and arson. For more information about ATF, go to or follow @ATFHQ on Twitter. Follow @ATFStPaul on Twitter for ATF news in Wisconsin, Minnesota, South Dakota and North Dakota.
