The Major Case Squad of Greater St. Louis has concluded its investigation into the death of a former Illinois State trooper, which resulted in the suicide of his son.
Swansea Deputy Police Chief Craig Coughlin said some follow-up work will be conducted by the Swansea Police Department.
It's still unclear what led to a physical altercation Monday between David L. Daughtrey, 61, and Jarad Daughtrey, 36, that directly contributed to the elder Daughtrey's death, according to investigators.
David Daughtrey's body was discovered at 1 p.m. Tuesday when Swansea police went to the home he shared with his son in the 200 block of Mimosa Avenue in Swansea for a well-being check. Suspicious circumstances at the scene prompted police to activate the Major Case Squad Tuesday night. However, police did not call Daughtrey's death a homicide, just suspicious.
His son Jarad Daughtrey was named a person of interest by police Tuesday night, and he was located early Wednesday at the Trailway Motel in Fairview Heights. After brief communications with police, Jarad Daughtrey shot himself in the head.
St. Clair County Deputy Coroner Danny Haskenhoff said an autopsy conducted Wednesday did not reveal a cause of death for David Daughtrey, who died late Monday. Toxicology results are pending.
David Daughtrey was a former Illinois State Police trooper, who went to work at Walmart in O'Fallon as a greeter following his retirement in 2002.
Brad Ireland, an event coordinator with Walmart Stores Inc., described David Daughtrey as "always such an up person.
"He will truly be missed, both by the employees at Walmart and the number of customers who became friends," Ireland said.
