How She Did it

"She could boldly call him late at night making my man to forget about me. I secretly took her phone number and when I called she insulted me," she began.
She went on to explain that she hired a man to befriend her target and paid for them to go on dates as she looked for an opportunity to finish her.
"The woman who proved to be a home wrecker gave in to the hired man's advances. I financed the man to host her on a date at a joint where I went and secretly identified her.
"I paid for a second date and directed the fake boyfriend to make sure she was drunk and booked her in a River Road lodging," she confessed.
