DOYLESTOWN, Pa. (AP) — Attorneys for a suburban Philadelphia tattoo artist charged with sex crimes involving more than a dozen children are set to begin presenting their defense.

The prosecution wrapped up its case against Walter Meyerle on Thursday.

Meyerle’s attorneys can begin their defense on Friday, although it may not take long. The defense has opted for the judge to review evidence and issue a verdict that could be appealed based on pretrial rulings.

Over four days Bucks County prosecutor Jennifer Schorn presented to the court victim testimony, a child pornography collection allegedly seized from Meyerle’s home and text messages he allegedly exchanged with one teen.

Authorities say Meyerle, of Falls Township, traded a tattoo for sex with a 15-year-old girl last year, sparking an investigation that led to additional charges.
