Montana ? The U.S. Fish and Wildlife Service says it is offering a reward for information leading to the conviction of whoever illegally shot one of Montana’s largest grizzly bears.

The carcass of the bear called Maximus because he stood 7 1/2 feet tall and weighed about 800 pounds was found Aug. 12 on a ranch in northern Montana. The bear had been dead about a month.

Special Agent Brian Lakes says the reward would be “substantial.”
