A Jefferson County Sheriff's Deputy was killed Saturday evening while mowing his yard.

James Lee, 71 of Hamshire, was pronounced dead on the scene.

According to the Sheriff's Office, a single-vehicle wreck was reported just before 8:15 p.m. in the 19000 block of Burrell-Wingate Road -- about four miles east of Texas 124.

A Toyota SUV was westbound when it "was traveling at an unsafe speed while attempting to negotiate a curve, at which point it traveled off the road into the ditch and struck a person operating a lawn mower," according to a news release from the Texas Department of Public Safety. 

The vehicle's driver, 38-year-old Michael Miller, of Beaumont, was taken to a local hospital for treatment and a mandatory blood specimen, police said.

Miller was arrested for intoxicated manslaughter and unlawful carrying of a weapon.

The sheriff's office is working with Lee's family to make funeral arrangements, which are expected to be shared later in the week.

"Jefferson County Sheriff's Deputy Jim Lee was a beloved long-time deputy who was known for his calmness and kindness," the Sheriff's Office said in a Facebook post. "His dry wit and humor will certainly be missed."

The Texas Department of Public Safety is investigating the crash.
