MOBILE, Ala. -- The mother of a teenager who is accused of gunning down a Mobile police officer has pleaded not guilty on a misdemeanor charge.
Police in Mobile say Tiffany Perez made up a story about her 19-year-old son, Marco Perez, being kidnapped.
Investigators say she was lying in order to help him evade capture from police.
Tiffany Perez is charged with filing a false police report.
While she did not appear in court herself today, her attorney -- James Byrd -- entered the not guilty plea on her behalf.
According to Byrd, his client is horrified about the shooting of Tuder. He said she was afraid her son had been kidnapped and murdered while he was on the run from police.
Related to the case against Marco Perez, police say the gun used to kill Officer Sean Tuder was stolen from an unlocked vehicle just a few days before the shooting.
Now the City of Mobile and the police department are teaming up for a new safety campaign. Authorities say they want to emphasize just how dangerous it can be to leave weapons in unlocked vehicles and risk them ending up in the wrong hands.
