Table schema:
CREATE TABLE table_name_96 (reported_offenses INTEGER, killeen_rate VARCHAR, texas_rate VARCHAR)

Question: Killeen Rate of 511.6, and a Texas Rate smaller than 314.4 is the lowest reported offenses?
SQL: SELECT MIN(reported_offenses) FROM table_name_96 WHERE killeen_rate = 511.6 AND texas_rate < 314.4
