CLEVELAND (AP) — Cleveland’s mayor says he didn’t trust a state agency to investigate the fatal police shooting of a 12-year-old boy who was carrying a pellet gun because he believes the agency mishandled a different shooting investigation that led to charges against officers.

The Northeast Ohio Media Group (http://bit.ly/1vS1I2W ) reports Mayor Frank Jackson explained Sunday how his thinking on the Tamir Rice case was influenced by the review of a November 2012 chase and shooting that ended with the deaths of two unarmed suspects.

Jackson says he asked the Cuyahoga (ky-uh-HOH’-guh) County sheriff to investigate Tamir’s death because he wasn’t confident a transparent investigation with due process would be conducted by the Bureau of Criminal Investigation and Ohio’s attorney general.

Messages seeking comment were left early Monday for the attorney general’s office.
