Florida shooting: Sister fatally shot over Christmas present row

Pinellas County Sheriff Bob Gualtieri gave an update to reporters on Tuesday night

Two teenage brothers have been arrested after their sister was shot and died during a row over Christmas presents.

Abrielle Baldwin, 23, was shot in the chest by one brother while she had her 10-month-old son in a carrier, the Florida sheriff's office said.

The brother was then shot by their other sibling, who pulled his own gun, Pinellas County Sheriff's Office said.

It added that the shooting followed an argument over who was getting more presents.

Sheriff Bob Gualtieri told reporters the older teenager, who is 15, ran from the scene and tossed his gun away.

The younger brother, a 14-year-old, was taken to hospital in a stable condition and will be taken into custody when he is released, police said.

Florida authorities said this is the gun that was used to shoot the woman

Local prosecutors will review the case and decide whether to charge him as an adult for the killing of his sister, Sheriff Gualtieri added.

The woman was taken to a hospital, where she was pronounced dead, Sheriff Gualtieri said.

He explained the mother-of-two suffered internal bleeding and was unable to breathe - but he added the baby in the carrier was not harmed.

The 15-year-old was arrested and charged with attempted first-degree murder and tampering with evidence.
