More details are emerging in the aftermath of the shooting deaths of seven people in an apartment near Fort Worth, Texas.

Police say six adult members of a family had apparently opened Christmas presents, just before a relative dressed as Santa Claus showed up and opened fire, killing them before killing himself.

Police went to the apartment Sunday after receiving a 911 call in which no one was on the other line. They found four women and three men, aged 18 to 60, dead.
