The Colorado State Patrol has recalculated the number of sheep that died in a San Luis Valley hit-and-run crash this week. Officials say a drunken driver killed dozens of animals.

Captain George A. Dingfelder said Friday at last check 42 sheep died in the Rio Grande County wreck. Officials initially said 38 were killed and 12 injured.

Lynn Ann Michel, 47, of Monte Vista was arrested. The State Patrol says she was westbound on Rio Grande County Road 8 South when she ran into the flock.

Michel fled the scene, authorities say, and was tracked down by troopers, who found the front license plate of the 2005 Isuzu sports utility vehicle she was driving.
