A Stephenville woman is in custody after allegedly firing a gun at a man during a dispute early Wednesday morning.

Stephenville police received a call about 3:45 a.m. Wednesday in reference to possible shots fired and a dispute between a man and woman in the 300 block of Morgan Mill Road, according to Lt. Doug McClammy.

When officers arrived, they met a male subject, identified as Oscar Colorado, 21, outside of the residence. The woman, Shana Martin, 21, was inside.

"Officers spoke separately with the two and learned that Colorado and Martin got into an argument outside of the residence," McClammy said "Sometime during the argument Martin got a weapon and fired a single shot in the direction of Colorado."

Although no one was hurt in the incident, Martin finds herself in serious trouble.

She has been charged with aggravated assault with a deadly weapon and is being held at the Erath County Jail on a $15,000 bond.
