The suspect is currently being held in a local hospital's mental health wing, according to sources. Public records show he pleaded guilty to criminal sexual conduct in 2010 and assault in 2015, receiving probation in both cases. Wix's brother and sister, Anthony and Alicya Wix, say the loss still does not feel real. It doesn't feel real. There's a lot on my mind and nothing on my mind at the same time, you know? Anthony Wix said. It ain't right. Never in a million years will we have thought this is what happened, Alicya Wix said. Alicya said her sister had been working hard to rebuild her life after struggling in the years following the birth of her daughter, Kacya, when Jaqouya was 17. Kacya's father passed away when Kacya was 1 year old. Unfortunately Kacya's father passed away when she was one, so she she struggled a bit after that making choices and figuring out how to being an adult and a mother, Alicya Wix said. Alicya said her sister had been living with her for the past year and had committed herself to being a better mother and employee - riding the bus to work every day regardless of the weather. She wasn't on the right path for a while, but I was always there to support her. She's been living with me for the past year, doing what she needs to do as a mom and a person and going to work every day, riding the bus to work faithfully every day, rain, snow #wxyz #CrimeInTheD ®
