A Colorado rancher was killed alongside more than 30 head of cattle when lightning struck Saturday in Jackson County, officials said Sunday.

Mike Morgan, 51, had just finished branding cattle and was starting to feed them from a trailer on Saturday when the lightning struck in Rand, about 80 miles northwest of Denver, according to the Jackson County Sheriff's Office.

The lightning strike knocked over some 100 cattle, but most of them got back to their feet. Morgan was killed, along with 34 animals.
