On May 14, 2015, Morrissey handed a photo to a reporter of himself, the teenage secretary with which he was accused of having a sexual affair and her baby. The reporter, Joe St. George with WTVR CBS 6 in Richmond, uploaded the photo to Twitter, eliciting confused questions from followers as to whether it was an admission of paternity by Morrissey, who had previously denied having an affair and impregnating the staffer. The reporter responded on Twitter that Morrissey had simply handed him the photo and said, "see you later." The photo features the three dressed in period costumes. The reverse of the photo, which was also posted to Twitter, contained a note that read, "To: Channe [sic] 6 From Myrna and Joe," with additional text scribbled out. The mother gave birth to the child in mid-March 2015, shortly after the former delegate completed a jail stint following an Alford plea to charges of contributing to the delinquency of a minor. She also appeared with Morrissey when he announced he planned to challenge Roz Dance in the Democratic primary for District 16 of the Virginia State Senate. Morrissey failed to qualify for the Democratic primary ballot due to insufficient valid signatures and so will run for the Senate as an independent. On May 20, 2015, Morrissey confirmed during a radio program that he fathered a baby with his former secretary.

A week after winning a special election to fill his own seat, Morrissey faced more criminal charges stemming from his relationship with a then-17-year-old receptionist from his office and the steps he took to explain his actions. Special Prosecutor William Neely announced on Wednesday, January 21, 2015, that Morrissey had been charged with four felony counts for perjury and forgery of court documents. According to Neely, the child support documents Morrissey used to explain his midnight encounter with the underage girl were made up. On December 12, 2014, Morrissey entered an Alford plea for a misdemeanor contributing to the delinquency of a minor charge. During his plea hearing, his defense entered into evidence a Chesterfield JDR child support order to prove his claim that the underage girl was at his house at midnight to discuss her father's failure to comply with court-ordered child support. But, according to the Commonwealth, the child support order was falsified by Morrissey. Morrissey was also being charged with persuading the girl's mother to vouch for the authenticity of the document in court. Deidre Warren, the girl's mother, is also facing perjury and forgery charges stemming from the plea hearing. His plea agreement covered all existing charges against Morrissy and requires him to spend his nights in jail. But, his plea agreement did not cover any new crimes, which is why Neely was able to bring additional charges against the Delegate. Morrissey turned himself into the Henrico County Jail on January 21st following the indictments. His bail was set at $2,000.

On June 30, 2014, a grand jury issued five indictments on felony charges of indecent liberties with a minor, possession of pornographic images of an underage female and of solicitation to obtain the images. Special prosecutor William Neely alleged that Morrissey had sex with a 17 year-old girl twice in his law office and texted someone about it. Morrissey's attorneys said that a secretary in the representative's law office erroneously claimed the girl was 22 and that no sexual activity took place. He was convicted of a misdemeanor and was sentenced to 12 months in jail with six months suspended. Gov. Ralph Northam (D) pardoned Morrissey on January 13, 2022.
