Police charged 33-year-old Glenn Doneghy with murder and assault and drug charges related to the death of Officer Bryan Durman.
27 NEWSFIRST has learned this isn't Doneghy's first arrest.
Doneghy's mental health and behavior problems are well documented at the Fayette County Jail where he's being held.
Doneghy has been arrested in Fayette County 22 times and charged with 65 crimes since 1995.
According to court documents, a warrant was issued for a probation violation after a robbery arrest in 2007. After serving 120 days in jail for stealing groceries and hitting a store employee with a bag of food Doneghy was push on probation under the condition he stay on medication.
The reason he was likely put on medication in the first place according to family members has to do with witnessing his mother's death.
At the age of seven he was in the car when his mother was pumping gas and caught on fire killing her.
Doneghy was awarded $1,000,000 in a settlement, but family members say he suffered irreparable psychological damage that led to a number of arrests and convictions on crimes of wanton endangerment, unlawful imprisonment and assault.
On Doneghy's arrest report, an alert has been issued for jail employees to watch out for mental health issues and behavioral problem.
Doneghy recently failed to appear for a hearing on April 16 on marijuana possession and resisting arrest.
He will be in court Monday on the murder charges.
Doneghy's cousin, Wanda, says she wants the community and family of the fallen officer to know they are very sorry for their loss.
