A jury has sentenced to death a 21-year-old man for killing a 5-year-old girl and her grandmother during a family birthday party in Fort Worth, Texas.

The jury condemned Erick Davila on Friday. He was convicted Feb. 19 of shooting 48-year-old Annette Stevenson and her granddaughter, Queshawn Stevenson.

Prosecutors say the two were killed at the woman's home during a birthday party for another grandchild.

Davila's attorneys say Davila had gone to the house to look for Queshawn's father who allegedly was a member of a rival gang. Four people also were wounded in the April 6 shooting.

The jury had the option of sentencing Davila to life in prison without parole.
