Maryann says she met her fiancé, Luis, on a dating website two years ago and five days after their first date, he professed his love, and they began planning a wedding. She says he told her he was a single millionaire and could give her anything she wanted. However, five months later, she says their relationship turned into a nightmare.

“Luis received a text, and it read, ‘When are you coming home?’ Come to find out, it was his wife,” Maryann claims. “I confronted him about the text. Luis hit the roof. He got so irate, so mad, he punched me in the kidney.”

Maryann says a week later, she got back together with Luis and she moved in with him and his wife. “Luis and I had separate bedrooms upstairs. His wife stayed downstairs,” she says.

Maryann says things went downhill from there. She claims Luis began a string of affairs with multiple women and that he began verbally abusing her, accusations Luis denies. Maryann claims she snapped and shot the man she calls her “lying, married, manipulative, narcissistic boyfriend.”

“It was self-defense,” Maryann claims. “I wasn’t in my right mind. I just wanted it to end.”
