SUGAR LAND, Texas- Rosenberg police say a Sugar Land man accused of stabbing his infant son Friday was already under investigation for allegedly sexually assaulting a student at the Lamar ISD school where he teaches.
Anthony Gilbert, 37, is a teacher at B.F. Terry High School.
An arrest warrant had been issued for Anthony Scott Gilbert, accusing him of having a sexual relationship with a 16-year-old student.
Then Friday morning, Gilbert was involved in a SWAT standoff with Sugar Land police after allegedly stabbing his infant son.
The standoff began after Jennifer Gilbert, 39, showed up at Sugar Land Methodist Hospital with the baby who had been stabbed several times. The 1-week-old boy was flown by Life Flight to Memorial Hermann Hospital where he is in critical but stable condition.
Jennifer Gilbert reportedly told police her husband held her and the baby hostage overnight. She managed to escape with the wounded baby.
When authorities arrived on the couple's apartment at 15700 Lexington, Anthony Gilbert held them at bay. A SWAT team was called and officers shot gas into the man's apartment, then rushed inside.
They say they found Anthony Gilbert unconscious with self-inflicted stab wounds. He was airlifted to Memorial Hermann Hospital in critical condition.
Officers say they don't know if he was unconscious because of the injuries or because of gas that was used during the entry.
Sugar Land police said the family does not have a criminal history.
They say the mother has a 2-year-old girl who was not injured.
