“Deputy DeRosier was a Kelso boy, his family has deep roots here,” said Cowlitz County Sheriff Brad Thurman.

The sheriff’s office said DeRosier graduated from Kelso High School in 2008. He went on to Washington State University in Pullman, Washington where he graduated in 2012 with a degree in criminal justice.

DeRosier’s career in law enforcement started in 2013 when he was hired by the Whitman County Sheriff’s Office, which services the Pullman area. He served there for three years on the SWAT team and as a boat operator.

He returned home in 2016 and joined the Cowlitz County Sheriff’s Office as a patrol deputy. Officials said he also worked as a boat operator, and was set to join the drug task force as a narcotics investigator on July 1, 2019.

The local community held a candlelight vigil for Deputy DeRosier at 7 p.m. at Lake Sacajawea in Longview. Attendees were encouraged to wear blue.

A memorial service will be held for Deputy DeRosier, however, it has not been scheduled.
