Alabama Sweet 16 Shooting: Fourth Person Charged with Murder.

A fourth suspect has been arrested and charged with four counts of reckless murder in connection with the mass shooting at a Sweet 16 party in Alabama that killed four and wounded 32 others. The arrest comes after two teen brothers and a 20-year-old man were arrested and charged on the same counts earlier this week. The motive for the shooting remains unclear, and more charges are likely to be filed. Four people who were shot at the party were in critical condition as of Wednesday.
