Nicholas Chavez, 27, was shot and killed on April 21. A cellphone video recorded by a witness appeared to show Chavez on his knees when he was shot by officers. “This case went before the independent review board somehow it slipped through their hands,” said Leantha Chavez, Nicholas Chavez’s mother. “It should be the Houston community and the voters to decide what is best for the Houston community,” said Johnny Mata of Greater Houston LULAC. The Houston Police Officer’s Union contract with the city also has provisions in it, which can be modified during negotiations next year with the city.
