A St. Louis-area woman says she doesn’t regret attacking a man with a bat because she believed he was selling her son heroin.

Sherrie Gavan was convicted Tuesday of a misdemeanor third-degree assault for striking the 22-year-old man with a bat in December 2011. She faces a fine of $1,000 and a year in jail when she is sentenced June 4.

Joshua Loyd admitted during the trial that he supplied Gavan’s son with heroin.

He also testified that he couldn’t remember if he was on heroin the day Gavan confronted him and he was not hurt in the attack.

Gavan says her son has been off drugs for more than a year and Loyd hasn’t contacted him since their confrontation.
