SPRINGFIELD, Mo. -- It all started with a conversation about vampires.
A man was curious about sucking someone's blood, so Victoria Vanatter, 19, allegedly gave him permission to cut her arm with a razor and drink some of her blood in the kitchen of a Springfield home.
The blood sucking, police say, was followed by arguing.
Court documents say there was some yelling and slapping before Vanatter grabbed a knife and stabbed the man several times.
Vanatter then "came to" and called 911, according to court documents.
Vanatter has been charged with first-degree domestic assault and armed criminal action in connection with the events that occurred Wednesday afternoon in Springfield.
According to a probable cause statement, Springfield police were sent to the home after a crying woman called 911 and said someone was bleeding.
When officers arrived, the statement says, they found Vanatter and the man covered in blood.
"I'm sorry" and a heart were drawn in blood on the wall in the living room, according to the statement.
The statement says Vanatter told a Springfield police detective that she drew the message in blood after stabbing the man several times.
Vanatter said at one point she tried to prevent the man from leaving the home because she was worried about going to jail, but she eventually realized she would go to jail anyway so she called 911, according to the statement.
Vanatter and the man were each treated at the hospital and received stitches for their cuts. Vanatter is now being held at the Greene County Jail on $150,000 bond.
The statement says Vanatter told the detective she is a threat to society and could be a serial killer in the future.
Vanatter was on probation in two other assault cases at the time of this incident, according to court documents. She does not have an attorney listed for this case.
The statement says the man, who is not named in the court documents, was not cooperative and told police his injuries were self-inflicted.
