Texas mom kills her 9-year-old daughter before turning gun on herself in Murder-Suicide

A Texas mother killed her nine-year-old daughter then herself in a shocking murder-suicide during an intense nine-hour standoff with police.

On Monday, police responded to a domestic violence call at the 500 block of Highcrest Drive in Red Bird, Dallas around 12.30am where they found a man who said he had been in an argument with his wife.

The man said he escaped the home when his wife, 34-year-old Alexica Stevenson-Gates, started shooting and 'chased him out of the house', barricading herself inside with her nine-year-old daughter and 12-year-old son, Dallas police say.

SWAT officers were able to negotiate for her to release the boy from the home.
