Police have arrested a man for killing his older brother in Garland.

Officers said 18-year-old Brendan Demarcus Edwards was having an argument with his brother, 26-year-old Ryan Christopher Smart, just before 4 a.m. Monday at a home in the 200 block of East Taylor Drive.

Edwards pulled out a gun, shot his brother, then left the house, according to officers. When police arrived, they found Smart lying on the floor with a gunshot wound. Smart was transported to a hospital where he died.

Edwards turned himself in later at the Garland Jail. He has been charged with murder. A bond has not been set.

The shooting is still under investigation.
