Dodge City police say a man whose body was found during the weekend was killed by a single shot to the head. Four people have been arrested in the death of 18-year-old Zacarias Giannino, of Dodge City. His body was found Sunday but police believe he was killed on Jan. 28. Police Chief Drew Francis says 19-year-old Tyree Jackson and 31-year-old Lakendria Lewis, were booked into the Ford County Jail on possible charges of first-degree murder. Two juveniles also were arrested. Francis says Giannino’s body was outside in a secluded area and cold temperatures since his shooting preserved the remains.
