CHARLESTON, W.Va. -- A Fayette County man surrendered to authorities early Thursday after a 4 1/2 hour standoff with police.

Fayette County Sheriff Steve W. Kessler said authorities are not yet releasing the name of the man, who is undergoing psychological evaluation following the incident in the Gatewood Road area. Fayette County sheriff's deputies say criminal charges are expected to be filed within the next few days.

According to a sheriff's department statement, emergency dispatchers were called about 9 p.m. Wednesday about a domestic disturbance between a man and his son. Deputies were told that one of the men had a gun and had barricaded himself in the house next door.

According to the statement, the man threatened to commit suicide, told deputies he had wired the house with multiple propane tanks and would kill any officer who tried to approach the house.

The sheriff's department tactical team and crisis negotiators were called in and made contact with the armed man by telephone at about 10 p.m. Negotiators talked to the man by phone until about 2:30 a.m., when he surrendered without further incident.

Deputies said the man fired about 15 rounds from a 9mm semi-automatic pistol during the standoff. Deputies also found six marijuana plants inside the house.

The man was taken to a local hospital and has not been charged pending the results of the psychological evaluation.
