A man that authorities say is suspected of being a graffiti vandal who tagged more than 300 sites around Phoenix over a 20-month period has been sentenced to one year in prison.

The Maricopa County Superior Court says 27-year-old Joel Delgado was also sentenced Tuesday by Judge Daniel Martin to four years of supervised probation after pleading guilty to Attempt to Commit Criminal Damage and Criminal Damage.

The state alleged Delgado was the worst graffiti vandal in Phoenix and allegedly tagged under the handle "Jugs" or "Jugz."

Prosecutors say Delgado was tracked and investigated using new technology that allows authorities to observe all the places he allegedly tagged, providing clues leading to his arrest.
