A 44-year-old tree trimmer was killed Wednesday after a tree limb struck his elevated platform and sent him falling more than 40 feet to the ground, the West Feliciana Sheriff’s Office said.

Calvin Lofton, of West Feliciana, was trimming trees near La. 10 on Joe Daniel Road in St. Francisville when the limb snapped back and hit his elevated bucket, causing the bucket to break away from the boom truck, said Erin Foster, a West Feliciana Sheriff’s Office spokeswoman.

Lofton was pronounced dead at the scene about 3:30 p.m., Foster said.
