NEW INFORMATION: Meth found in man killed in officer-involved shooting near Menomonie

By  | 

MENOMONIE, Wis. (WEAU) -- A new report shows a man killed in an officer-involved shooting had enough meth in his system to be in a "near toxic range" when he died.

Dunn County Medical Examiner Chris Kruse announced the findings regarding Dennis Grohn, 32, of Dunn County on Tuesday. In a news release, Kruse says both methamphetamine and amphetamine were found in Grohn's blood and urine. The findings led Kruse to believe that Grohn was "heavily under the influence" of meth when he died. He also believes Grohn had been using meth "for some time" before he died.

Officers shot and killed Grohn in February. They served a "no knock" warrant at Grohn's home in the Town of Red Cedar to look for drugs. Investigators say a deputy shot Grohn after Grohn charged at him. The two struggled on the floor of the garage. Another officer got there, and saw Grohn's hand on the deputy's rifle, so he shot Grohn. An autopsy determined Grohn died of two gunshot wounds. The state Department of Justice investigated, and a prosecutor determined that both officers were justified in their actions.
MENOMONIE, Wis. (DUNN COUNTY MEDICAL EXAMINER'S OFFICE NEWS RELEASE) --Final autopsy and toxicological results are available concerning the death of Mr. Dennis B. Grohn.

The blood analysis was positive for amphetamine at 0.11 mg/L, and methamphetamine at 0.77 mg/L.

The urine screen was positive for amphetamine at 8319.50 ng/ml, and methamphetamine at 57349.00 ng/ml.

No ethanol was detected.

This toxicological analysis reviles (sic) Mr. Grohn was heavily under the influence of methamphetamine at the time of his death. The 0.77 mg/L blood level of methamphetamine represents a near toxic range (fatalities have been reported at 0.8-2.0 mg/L). Further, it is determined based on the urine level that he had been using methamphetamine for some time prior to his death.
