A mother in Idaho has been arrested for felony injury to child, and police said she tried to justify "jolting" her 1-week-old daughter by saying that she is "not made of glass." Brenwyn Richey reportedly told a witness that "people do it all the time" when she was caught "shaking and jolting" her baby daughter like a rag doll, according to a probable cause affidavit obtained by Law & Crime. Witnesses allegedly told authorities that they saw Richey, 26, yanking the girl by her leg and bouncing the child aggressively on her knee on several occasions.
