Court documents allege that a man’s blood-alcohol level was double Kansas’ legal threshold when he caused a crash that killed a Johnson County sheriff’s deputy.

The Kansas City Star reports Adrian Espinosa-Flores’ blood-alcohol content measured .160 after the Sept. 11 crash.

Espinosa-Flores is charged with involuntary manslaughter and leaving the scene of a fatality traffic crash in connection with the accident that killed Master Deputy Brandon Collins.

Collins was conducting a traffic stop on U.S. 69 in Overland Park when authorities say a pickup truck driven by Espinosa-Flores ran into Collins’ parked patrol vehicle from behind.

Adrian Espinosa-Flores told police he had been drinking beer at a friend’s house before the crash and that he was in the country illegally.

His public defender hasn’t returned messages seeking comment.
