AUSTIN, Texas (KIAH) – A registered sex offender has escaped custody again, this time from a hospital in Austin. Investigators say McArthur Deashy Mathis kicked open a door and scaled a six-foot fence to flee from a medical facility where he was being held. The Grimes County Sheriff said Mathis had been transferred to that hospital following another inmate’s escape from a North Harris County hospital in March. Authorities are now searching for Mathis.
