Cesar Pantoja, a 23-year-old resident of Greenfield, California, was killed on October 16, 2012, after a gunman opened fire in the driveway of his home on Clifton Court during a gathering. Pantoja and four others were struck, including a 14-year-old boy, two 19-year-old men, and an 18-year-old man. Responders found Pantoja and another victim with life-threatening injuries; Pantoja was pronounced dead at the scene.

Witnesses said the shooter fired from a neighbor’s yard and then fled in a light-colored sedan driven by an accomplice. A hostile crowd formed at the scene, obstructing emergency personnel and prompting police to call for substantial backup to secure the area. Authorities detained two people for questioning and later arrested a 42-year-old woman, Christine Lee Hendrickson, who was believed to be the getaway driver. The motive was not immediately clear, though some suggested a personal vendetta.

Does anyone who knew Cesar or who was in that neighborhood the night of October 16 have information that could help investigators?
