LYNN – A judge ordered $2,500 cash bail for a city man a prosecutor said filmed a sexual encounter with an unsuspecting woman and then – after he told her this and she got angry – threatened to post the video on Facebook.Bryan C. Rauscher, 29, of 195 Union St., was arrested and charged with carrying a dangerous weapon; photographing an unsuspecting nude person; and on a warrant charge at 8:59 p.m. Monday.Rauscher was arraigned on the non-warrant charges Tuesday in Lynn District Court and a plea of not guilty was entered on his behalf.”Not only did the victim give a statement she had no idea he was filming her while having sex with him,” Assistant District Attorney Shailagh Kennedy said Tuesday in Lynn District Court. “But he also threatened to post that video, that info, on Facebook.”But a defense attorney suggested the alleged victim was trying to get back at the defendant because he refused to commit to a relationship.”She doesn’t like the fact that they are not in a dating relationship and that was the cause of the argument,” court-appointed Defense Attorney Nick Morris said.A woman told police on Monday evening that Rauscher had told her he had used his cellphone to videotape the two of them having sex, Kennedy said in Lynn District Court Tuesday, summarizing from a Lynn Police report.Kennedy said the woman reported she and Rauscher argued and Rauscher threatened to download the video to Facebook “so that everyone could see it.”The woman told police Rauscher had done this “for no reason” as the alleged incident was the only time the two had been intimate, Kennedy said.The woman told police Rauscher also had a warrant for his arrest. Police confirmed Rauscher was wanted in Worcester on a shoplifting charge at Family Dollar where he had a folding knife clipped to his pocket, Kennedy reported. She requested $10,000 cash bail. She cited the defendant’s record includes convictions for assault charges in both district and superior courts, a history of violating restraining orders, “and the list goes on.”Morris agreed the allegations were “very concerning.” But he also cited several reasons why he said “if you read between the lines ? there is some sort of motive here that she’s trying to be vindictive about.”He noted the woman reported the allegations to a police officer she happened to see walking on the street on a date three days after the alleged sexual encounter occurred. Morris also said the woman mentioned the warrant to ensure Rauscher would be arrested. Morris also said police did not report seeing a video nor issue a search warrant to see if the video even exists.(Kennedy acknowledged officers did not report seeing an actual video but seized two cellphones for evidence that Rauscher was carrying when he was arrested).Judge Matthew Machera asked Morris to state what he was implying.Morris responded the woman did not like that Rauscher was not dating her.Morris requested Rauscher be released or be ordered a small amount of bail to answer the warrant charge. He also said Raucher was trying to turn his life around: Raucher was attending a residential drug-treatment program, had received federal student aid to attend North Shore Community College this fall and had, lately, “been doing all the right things.”Machera ordered $2,500 cash bail and ordered Rauscher held overnight to appear in Worcester today. Rauscher is scheduled to return to Lynn District Court Sept. 5.
