A Casper woman is denying charges that she stabbed her boyfriend, and is claiming she is not in the right mental state of mind.

Forty-two year-old Cathy Long has pleaded not guilty by reason of mental illness, and not guilty to one charge of aggravated assault and battery.

Investigators with the Casper Police Department say in July, Long stabbed her boyfriend in the chest with a knife.

The boyfriend says it was the result of a psychotic episode and the police reported she was not completely coherent during questioning.

The stabbing came after an argument over the death of one of his friends.

It culminated with her allegedly following him outside with a knife and plunging it into his chest.

The wound was about an inch deep and was not serious.

Long is being held on $5,000 bond awaiting trial, and could face up to 10 years in prison if convicted.

A judge has ordered her to undergo a mental evaluation.
