The Humane Society of the United States is offering a reward of up to $5,000 for information leading to the arrest and conviction of who was responsible for shooting fireworks that sparked a grass fire and killed four calves in Michigan's Thumb.
The Sanilac County Sheriff's Office said fireworks shot from a moving vehicle sparked the grass fire July 28 along a rural road in Greenleaf Township, about 85 miles north of Detroit.
Molly Tamulevich, Michigan state director for the Humane Society, issued a statement saying: "This callous act led to the painful death of four young animals."
The Humane Society says it doubled its standard cruelty reward from $2,500 to $5,000 because of a donation from a board member.
