Texas mom accused of handcuffing, seriously injuring 3-year-old son

According to KHOU and Harris County court documents, Savanna Nicole Coats, 25, of Houston was charged with serious bodily injury to a child after police say she handcuffed the boy's ankles last month, then misplaced the key. After searching for the key for five hours with help from Steven Joe McGaha, the boy's father, Coats held down the crying boy as McGaha "tried to cut the handcuffs with a sawzall, followed by a knife sharpener, then ultimately was successful when using a grinder," court records say.

KHOU reports that Coats' children have been placed in foster care. 

Coats, who was booked Wednesday, is being held at the Harris County jail without bail. As of Wednesday evening, no charges had been filed against McGaha, KHOU reports.
