It's guns again. People and guns.
Police believe that 22-year-old Manuel Ortiz and his 19-year-old sister, Savannah Ramirez, had been drinking.
They came back to an apartment in Phoenix, Ariz. As the local ABC15 TV reports it, this was an after-party party.
They were allegedly playing with a gun. They were posing for pictures to be uploaded onto Facebook.
Then gun went off. Manuel Ortiz is dead. He was shot in the head.
ABC's reporter said that Ortiz's sister was sitting at the curb after the shooting, sobbing and admitting that she had accidentally shot him.
The Daily Mail quotes Phoenix Police Sgt. Steve Martos as saying: "Every New Year's Eve, this particular sister is going to be thinking about this for the rest of her life on how...drinking overnight, playing with a gun and now shoots and kills her brother."
Both her and her brother's Facebook pages contain several shots of them posing with guns.
In one of them, Ortiz is pictured with a gun pointed to his head. He is wearing a t-shirt with the word "Famous."
It is unclear if the people involved knew that the gun was loaded.
Police say that Ramirez is now likely to be charged with manslaughter.
