EUREKA, Ill. (AP) — A Bloomington high school teacher has been charged with first-degree murder in her husband’s stabbing death.

Bond is $1 million for 30-year-old Sarah Mellor of Bloomington, who teaches Spanish at Bloomington High School. Prosecutors say 31-year-old Mark Mellor of Bloomington was stabbed late Saturday during an argument with his wife at a private campsite in rural Woodford County. Sarah Mellor remains jailed at the Woodford County jail in Eureka.

Prosecutors say relatives drove Mark Mellor from the campsite to a hospital where he was pronounced dead at 12:15 a.m. Sunday. The McLean County coroner said preliminary autopsy results found he died from a stab wound to the chest.

Court records don’t list an attorney for Sarah Mellor who could comment on her behalf.

School officials say they’re making counselors available for students.
