A former Aldersgate Enrichment Center employee was arrested Monday on allegations that he sexually assaulted two mentally disabled residents when he worked there, sheriff’s officials said.

Marshall Thornhill, 33, of Brownwood, was arrested in Lubbock on two indictments for aggravated sexual assault and brought to the Brown County Jail, sheriff’s officials and Brown County Jail records state. Thornhill is free on bonds totaling $80,000.

The indictments allege a total of five counts of aggravated sexual assault, jail records state.

Thornhill, who worked as the director of development at Aldersgate, resigned after the allegations, sheriff’s officials said.

According to an email from the sheriff’s office:

The parent of a female resident reported to sheriff’s officials on Sept. 20, 2019 that her mentally disabled daughter had been sexually assaulted.

The parent said her daughter reported she had sexual contact on multiple occasions with man identified as Thornhill, sheriff’s officials said.

The sheriff’s office began an investigation and learned of a second mentally disabled resident who was alleged to have been sexually assaulted by Thornhill.

Thornhill resigned his position at Aldersgate immediately following the sexual assault report.

The case was presented to the Brown County Grand Jury on Jan. 23, and the panel returned the two indictments with a total of five counts against Thornhill.

The Aldersgate Enrichment Center is three miles southeast of Early and is situated on 150 pastoral acres of partially wooded ranchland.

The center’s mission is to “establish and maintain a family-oriented Christian community that provides opportunity in all aspects of life for adults with special needs," the center’s website states.
