GALVESTON, TX --Family members are broken up after the sudden death of a 2-year-old boy and the arrest of his mother. And we've learned a second suspect in the case is now in custody. Investigators say the little boy was found injured at his home last weekend in Galveston, and just yesterday his mom was arrested. Then there was another break in the case today. Relatives say they didn't know what happened until a few days after the toddler died. Now the mother and her boyfriend are charged in the crime and relatives are planning a funeral. Ashlie Blanks says she can't believe her little nephew is gone. "I just enjoyed him all the time, he was sweet," Blanks said. She kept 2-year-old nephew Traeshon Dewayne Young many times at her Houston home and says she was anxious for her sister Porshe Mitchell to move back from Galveston so she could spend more time with him. But that plan has been turned upside down. "You don't mistreat children. They are a blessing from God," said Blanks. Galveston police were called to a home last Sunday and found Young unresponsive. He later died. "He didn't deserve to be abused. He shouldn't have been abused. He should have been loved and cared for," Blanks said. She says her sister told her that her boyfriend had been watching him while she was at work. After days of questioning police began putting the story together. Yesterday they arrested Mitchell in La Marque and charged her with endangering a child and injury to a child. "I've lost two people because if they give her the time they are going to give her, she is gone away for a long time.," Blanks said. They also arrested Mitchell's boyfriend, Dontrel Alexander Sanders, on charges of injury to a child causing serious bodily injury. Now this aunt and mother of four is having a hard time making sense of it all. "He didn't even get to finish life. I was looking forward to looking at him at graduation and watching him go across the stage," said Blanks. The victim has a younger 1-year-old brother who is in the custody of Child Protective Services. Blanks says she'll seek custody of him.
