FORT ATKINSON, Wis. (WITI) -- The Bureau of Alcohol, Tobacco, Firearms and Explosives on Monday offered a reward of up to $10,000 for information leading to the arrest of Kevin Anderson, 62, wanted in connection with the murder of his sister and her husband and for setting his deceased parents' house on fire on June 16.
Anderson is described as a white man standing 6 feet tall, weighing about 200 pounds, with blue eyes and thinning brown hair.
According to a criminal complaint, deputies were called for a potential burglary in the Town of Sumner on June 16 at around 5:45 p.m. The caller, Nedra Lemke, told dispatch that she and her husband, Jim, had arrived at a property to mow the lawn and noticed broken windows, suspecting a break-in.
When authorities arrived approximately 12 minutes after the call, a sheriff's deputy approached an SUV parked in the driveway and found a man and woman deceased on the driveway.
The victims in the driveway were later identified as Nedra and Jim Lemke -- Kevin Anderson's sister and brother-in-law. The Milwaukee County Medical Examiner's Office determined both victims died from multiple gunshot wounds.
