The medical examiner says State Rep David Brumbaugh of Broken Arrow died from severe coronary artery atherosclerosis, and his manner of death is natural.
Brumbaugh, 56, died after collapsing at his home on Saturday, April 15, 2017.
He was the vice chair of the House Appropriations & Budget Subcommittee on General Government.
His fellow lawmakers honored him last month, a few days after he died. The state House of Representatives observed a moment of silence for Brumbaugh.
Lawmakers wiped away tears as they remembered Brumbaugh as a man not everyone always agreed with, but someone they could all respect.
