A lie detector could show that suspect Giovanni Ramirez was not one of the two men who attacked Bay Area Paramedic Bryan Stow on the opening day of baseball at Dodger Stadium last month.
Lawyers for Ramirez said Tuesday that they've emailed other evidence to authorities that shows police have the wrong man in custody.
The evidence includes statements from 11 witnesses who contend Ramirez was elsewhere when the attack took place.
"What we've tried to do is account for his whereabouts," said Ramirez' attorney Anthony Brooklier.
Co-counsel Jose Romero alleged there are multiple locations "with witnesses that are confirming that the story lines that we forwarded are in fact true."
The lawyers would not say whether they've hired a polygraph examiner although Ramirez has said he wants to take a lie detector test.
Polygraph expert Jack Trimarco, who once headed the FBI's polygraph unit, has not examined Ramirez --but he warned that four out of five suspects who take such tests fail.
Polygraphs are not admissible in criminal courts in California so there is no downside for a suspect to take such a test.
All a defendant may lose is the fee he paid to the examiner.
That fee could run $2,500 and it might be seen as a good investment, if the defendant actually passes the test.
