“One of the ways Ashleigh begs for attention is when she makes up lies about everyone in her life either abusing her, molesting her, or raping her,” says Krysti in the video above. She claims Ashleigh has never gone to the police about any of the alleged assaults against her.

“She’s trying to prove that I’m lying in saying that I haven’t been abused,” says Ashleigh of her sister-in-law, Krysti. Ashleigh asserts she’s been abused multiple times, since the age of three.

Krysti also accuses Ashleigh of being “on drugs,” and plotting to take her infant son. Ashleigh denies both allegations.
