CUSTER COUNTY, S.D. - Authorities have released the names of two north-central Nebraska men who died in a UTV crash south of Custer, South Dakota.

Curtis Shawn Malone, 60, of Long Pine, and Shawn Lee Malone, 41, of Ainsworth, were killed in the crash on Sept. 1.

According to the South Dakota Department of Public Safety, Curtis was driving a 2023 Can-Am Maverick Side-by-Side south on Flynn Creek Road when he failed to negotiate a curve. The vehicle slid sideways on the gravel, went into the east ditch, and struck a tree. Both men died at the scene.

Officials say both were wearing seatbelts. The South Dakota Highway Patrol continues to investigate, and information released so far is considered preliminary.

An online obituary states that Curtis was Shawn’s father. It also notes that a Celebration of Life for both men will be held Sept. 20 at noon at the American Legion in Ainsworth.
