Authorities have identified the tree service worker killed on the job yesterday in Magalia as 43-Year-Old Abraham Cuevas from Live Oak. He was killed yesterday morning while doing work on a tree in the yard of a home on the Skyway in the Lovelock area of Magalia. Cuevas was approximately 40-feet in the air attached to a safety harness when coworkers say part of the tree fell and hit him. Cuevas was hanging from the tree until workers eventually got him down and neighbors attempted CPR, but Cuevas was pronounced dead at the scene. CAL OSHA is investigating the incident.
