Walworth County deputy on administrative duty after fatal shooting
"The deputy has been placed on administrative duty, which is normal procedure, pending the outcome of the investigation headed up by DCI," Graves said.
DCI is the Division of Criminal Investigation at the state Department of Justice.
The deputy responded to a 911 call shortly after midnight Saturday from a residence at 1463 Meadow Lane. The homeowner reported that her adult son was threatening suicide and was armed with a knife.
Graves said John W. Brown was armed with a knife, threatened deputies and refused to drop the weapon. A deputy shot Brown, who was pronounced dead at Aurora Lakeland Medical Center in Elkhorn.
Graves said it is standard procedure to call in a neutral agency to investigate incidents involving the discharge of a firearm by a deputy. He said similar situations have happened in the past, but there's no way to predict how long the investigation will last.
"DCI agents were on the scene quickly, but crime lab personnel had to be called in from Waukesha County and did not arrive until Saturday night," Graves said. "All their findings and evidence must be processed.
"When they get to that could be determined by their workload, so there's no way to predict how long the investigation will take," Graves said.
