Stepfather Sodomizes Son Who Sodomized His Daughter
In the ultimate case of retaliation, a father in Arlington is charged with aggravated sexual assault after sodomizing his stepson in revenge for the son sodomizing his 8-year-old stepsister.
On the night of January 2nd, the father caught his 18-year-old stepson assaulting his 8-year-old daughter and called police. The son was arrested and the father issued a warning to his wife not to bail the son out of jail. She ignored him. Much to the father’s surprise, he was the lucky recipient of the son’s call from jail asking for a ride home the next day. Soon after retrieving the son from jail, the father took him to an abandoned home in east Fort Worth to handle things in his own manner; he brutally beat his stepson with a baseball bat and anally raped him with a wrench-like metal tool. The father turned himself in to authorities on Friday but was released after posting a $17,500 bail.
Supervisor for the Fort Worth sex crimes unit Sergeant Cheryl Johnston confirmed that there was “evidence at the scene to corroborate the victim's story” but also stated that “no one can take the law into their own hands.” Or other orifices.
