Louisiana state police are considering issuing a statewide Amber alert after a suspect in the killing of four people and the kidnapping of three girls in Georgia was spotted in northwest Louisiana. Captain Mike Edmondson says the man matched the description of 31-year-old Jerry William Jones. Jones is the father of two of the missing girls and former stepfather of the third. Jones is accused of killing his ex-wife`s parents and sister, as well as his own infant daughter. He allegedly abducted 10-year-old Brittany Phelps, 4-year-old Brandy Jones and 3-year-old Tammy Jones. They were last seen yesterday at a home in Ranger, Georgia, 55 miles north of Atlanta. Edmondson says the man was spotted around noon in the Shreveport area. The Georgia Bureau of Investigation says the three girls are believed to be in extreme danger. Jones was said to be driving a maroon or red 1991 Ford Explorer with Georgia licence plate 730-YFV.
