A Venice man has been arrested for the second time on child pornography charges. 48-year old Mario Guerrero was first arrested in June and after further investigation, detectives discovered 16 additional videos containing child pornography on his computer. Deputies searched Guerrero’s home on Pine Tree Road earlier this summer after detectives investigating Internet crimes against children traced his IP address to 53 files that contained child pornography. He was arrested again over the weekend and charged with additional crimes.
