The case against Shawn Gaston and Kevin Walker was continued until Friday. The judge did grant the state's request to have both men fingerprinted.
"It's way too early to know of anything specific even the state doesn't have sufficient fingerprints to do the case so we are way to early to come to any conclusions," said Joel Brodsky, Gaston's attorney.
Defense lawyers say neither Gaston nor Walker fired the fatal shots that killed officer Valadez.
But police say both men have given statements admitting their involvement in the crime.
