Police this morning arrested a 27-year-old woman, Mary Catherine Della-Paolera, on charges linked to extensive graffiti discovered May 11 in a north Medford neighborhood in which she lives.

Medford police Lt. Tim Doney said the woman turned herself in after she became aware that police had received a tip about her identity.

Della-Paolera lives within a block of the targeted homes in the 400 block of Hayes Avenue with her boyfriend. Officers say they don't know why the targeted properties were chosen, and the incident appears to be random.

"We are not ruling out that there may be other suspects," said Doney.

Doney said the woman is being lodged in Jackson County jail on two counts of first-degree criminal mischief.
