A state agency says it stopped using a restraint board after a 15-year-old boy died at the Mexia State School when he was improperly restrained.
Spokeswoman Cecilia Federov says the Texas Department of Aging and Disability Services quit using the Transboard on Jan. 15, the day the boy died.
The device consists of a board with six straps for the arms, torso, legs and ankles.
Adelaide Horn, the department's commissioner, informed a state Senate committee last week of the boy's death.
She said the three staff members who improperly restrained the boy were fired after she received the autopsy and investigative report.
No charges have been filed in the case, but it has been referred to Limestone County officials.
The department cares for residents with mental retardation and developmental disabilities.
State officials refused to release the boy's name.
