PRINCE GEORGE, Va. (WRIC) -- A mother is grappling for answers after her son died inside Prince George County's Riverside Regional Jail. Twenty-eight-year-old Dartellee Foster was found unresponsive in his cell on Oct. 25, but his mother said she's gotten close to no information about what happen ed since then or why he was even in jail in the first place. Jovette "Cheyanne" Williams said her son was at Riverside for 10 days before he died.   She told 8News Foster was experiencing a mental health crisis and that he wasn't given his medication for his bipolar and schizophrenia diagnoses.   Now she's left piecing together what happened to her only child.   She described Foster as quiet growing up, who loved to draw and play video games, and was always willing to help anyone.     "He was very family-oriented. He loved his family," Williams said through tears. "Each day I keep thinking he's gonna call me and say, 'Hey, I'm at a hospital and I'm not dead.' It's just been mind-wrecking."  (Photo: Dartellee Foster) Williams said Foster's bipolar disorder and schizophrenia were something he had a good hold of with the help of medication and a psychiatrist he'd seen for years at Virginia South Psychiatric and Family Services.    She didn't even know why Foster was in jail. There are no charges listed for him on online court records, and police in Hopewell where he was living said they don't know what landed him in jail.   According to their records, Hopewell Police's last interaction with Foster was on July 26. Medical professionals obtained an emergency custody order, which led to him being placed on a temporary detention order. The last time he was arrested was on July 9, 2023, for assault and battery.  Williams didn't know where he was until she missed a call from Riverside's number.   "I immediately called the jail and I said, 'Look, he's having a mental health crisis. He needs his medication. What can we do to get him the medication that he needs?' They kept telling me, 'He's here in booking and he's not speaking to anyone,'" she said.   Williams called the jail 21 times during the 10 days Foster was there, trying to get him help, until a call on Oct. 25 came through.   "It wasn't until the morning of the 25th when they called me and said he had passed away that I heard anything from anybody associated with the jail," Williams said.   Charlene Jones, a spokesperson for Riverside, said Foster was found unresponsive in his cell early that morning. Medical staff performed CPR, but he was pronounced dead a little over 20 minutes later.    Jones did not answer our questions about what mental health treatment or medication Foster was given, if at all.   According to the Virginia State Board of Local and Regional Jails, four people died in Riverside in 2025. That's more than at any other jail in the commonwealth besides the Richmond City Justice Center, where four people also died.  "To know that someone that was so good was taken for no reason when I tried to get him the help that he needed. I called every day. I spoke to the magistrate. I spoke to medical. I spoke to the mental health department. I spoke to everyone, and no one provided him with the help that he needed," Williams said.    The Office of the Chief Medical Examiner will determine an official cause and manner of death. It's currently pending.   Williams said Foster had no underlying health conditions. She said she's looking into getting an attorney and wants all documentation about her son's time at Riverside.   ...read more read less
