Photos: Woman kills cheating millionaire husband after being mock by his mistress

A woman who killed her cheating millionaire husband in a road rage attack was sent thousands of taunting messages by his mistress, including videos of the pair having sex, before she drove him off the road.

Frances Hall, 53, was jailed for two years in September after being convicted of killing her estranged husband Bill Hall Junior in San Antonio, Texas.

Her husband's younger lover, Bonnie Contreras, now 34, is accused of taunting Hall with the messages but insists she is 'not a bad person'.

Ms Contreras allegedly sent the wife videos of her having sex with Hall's husband and pictures of hysterectomy diagrams saying Hall was broken, disgusting and not a real woman anymore, according to Hall's attorney, Leigh Cutter. 

In an emotional interview from behind bars, which is set to air on Crime Watch Daily with Chris Hansen on Tuesday night, Hall said she still loves her slain husband.

"The times he was leading this secret life, he made sure I was his number one,' she told the program. 

I love him and he is the only man I will love this way. Sometimes, I tell my kids that all that’s left of me is a shell of a woman. But I have to be there for them, they lost their father."

The couple were married for 34 years and have two adult children. His affair with Ms Contreras lasted three years.

The taunting all came to a head when Hall saw Ms Contreras driving their family Range Rover on a stretch of Texas Highway.
