BAKERSFIELD, Calif. (KGET) -- A man whose 3-year-old son got hold of an unlocked gun and accidentally shot his 6-year-old sister in the leg was sentenced Thursday. Ruben Guerra, 27, was sentenced to 96 days time served and four years of probation, and was ordered to attend a one-year child abuse treatment program. He pleaded no contest last month to two felonies: child cruelty and criminal storage of a firearm.
