Boulder County Coroner Emma Hall has concluded her investigation into the four people who died as a result of September's flooding, ruling all four of the deaths accidents.

According to a news release, Hall ruled that Wesley Quinlan, 19, of Erie; Wiyanna Nelson, 19, of Lafayette; and Gerald Boland, 80, of Lyons, all died due to drowning. Hall ruled that the fourth victim, Joseph Howlett, 72, of Jamestown, died of blunt force injuries to the head and chest.

Quinlan and his girlfriend, Nelson, were driving home with friends Sept. 11 when their car got caught in a mudslide near Linden Drive just west of Boulder. The two teens got out of the car but were swept away by the flood, and their bodies were discovered the next day.

Quinlan had just graduated from Centaurus High School, and Nelson was a senior there.

Boland's body was found a week after the flooding in the St. Vrain River bed on the 1000 block of Apple Valley Road, a few hundred yards downstream from his home. Boland, a former Lyons basketball coach and longtime teacher, had been reported missing after his family evacuated Lyons.

Howlett, former owner of the Jamestown Mercantile, was killed Sept. 11 in Jamestown when the building he was in collapsed.
