GEORGETOWN (CBSDFW.COM) - Police have arrested two people in the murder of a Bedford teenager.

The body of Tynesia Brown was discovered November 14 about 150 miles south of the Metroplex, near Jarrell.

Yesterday, police arrested 20-year-old Tracy Marie Guzman, of Birmingham, Alabama.  That follows last week’s arrest of 26-year-old Darius Lamar Davidson of Dallas.

Williamson County Sheriff’s Department Sgt. John Foster says Brown, Guzman, and Davidson were driving in Davidson’s car on I-35 when the two women got into a fight.

Guzman shot Brown, according to Sgt. Foster, and Guzman and Davidson then drove to the location near Jarrell and dumped the body.

Davidson is in the Williamson County Jail on $250,000 bond.  Police arrested Guzman in Birmingham yesterday, and they plan to bring her back to Williamson County soon.
