A fourth suspect has been arrested in connection to the Sweet 16 shooting that killed four in Alabama over the weekend, officials announced Thursday.

Johnny Letron Brown, 20, of Tuskegee, was taken into custody and charged with four counts of reckless murder, the Alabama Law Enforcement Agency (ALEA) said.

Brown’s arrest comes one day after two teen brothers and another 20-year-old man were arrested and charged in relation to the Dadeville massacre.
