Skinner was on anti-psychotic medication for a major depressive order but had stopped taking the drug before he tried to break into a US home, his friends have said.
Police allege Skinner tried to break into the teen's home and was shot by the girl's mother.
Skinner had been communicating with her online and travelled across the world to see her, despite the teenager's efforts to end communication between the two.
He was initially charged with a single count of breaking and entering with the intent to rape, rob or murder with a deadly weapon. The maximum penalty for the charge is life in jail.
Skinner had been under 24/7 police watch at VCU Medical Center while receiving medical treatment.
Deputies later transported Skinner to the medical unit at Henrico Jail East in New Kent County, WRIC reported.
