Lawyers for an American man accused of possessing child pornography and soliciting prostitution from four teenaged boys lodged a motion for dismissal with Preah Sihanouk provincial court on Monday, citing a lack of evidence. Alan Arthur Perry, 57, who has been held in pretrial detention since April 30, has denied all charges against him. Ben Hutchins, a spokesman for Perry’s legal team, said there are “serious concerns” over the lack of evidence submitted to the court.
