It is true that Sherre Gilbert, Shannan Gilbert’s sister, was assaulted by her mother’s lover when she was a little child. As children, Sherre and her sister Sarra experienced molestation. The man who had been her mother’s then-boyfriend was a bad guy.
Any child can experience trauma from events like that. Nevertheless, a lot of people who have been looking into the Gilbert family saga feel certain that Sarra’s mental health issue was caused by this horrific childhood event. Sherre, however, claimed that Mari’s murderer’s sister had only been mentally ill for 2.5 years at the time.
