Tanya Knower, 27, and her fiance of 11 years, 34-year-old Richard Hartman, lived at Hartman's mother's home
Knower and Richard Hartman had their two disabled children living in the home with them, family members told WDSU.
Strain said the argument centered on Knower's threat to take her kids and leave.
This is my mother i lost the best thing to ever happen to me over a stupid arguement i miss her so much my life will never b the same i lost my mother also but she deserves what she gets. I love my mother but will never forgiv or have contact hurting me is one thing. Hurting my babies and my wife of 11 years is not forgiveable.
