Monica Moynan vanished at the age of 22 in April 2019. The mother-of-two was living in Holly Springs, North Carolina at the time of her disappearance. Monica was last seen in person by 44 year-old Brian Sluss--her boyfriend and father of her two daughters. However, from April to June 2019, Monica's family members and friends continued to receive text messages from Monica's phone. Her mother grew slightly concerned when she noticed that Monica had stopped calling her--as she previously would call at least once every two weeks. Still, the texts Monica's family members and friends received seemed to match Monica's normal texting style, so they were initially not too worried.
That all changed in early July 2019, when the manager at Monica's apartment called her mother and expressed concern for the young woman. The manager had reportedly seen Brian Sluss at their apartment numerous times, but had not seen Monica at all since late March 2019. A welfare check was requested, and when police were unable to pinpoint Monica's whereabouts, she was reported missing.
When police questioned Brian, he told them he had last seen Monica in June 2019. He said that she had grown addicted to heroin and ran away. Brian also admitted to sending texts from Monica's phone pretending to be her--but he claimed to do that because he did not know how to tell her mother that she was addicted to heroin and had ran away.
As police continued to investigate Monica's disappearance, they determined that Monica had actually not been seen since April 2019--and that Brian was the last person to see her. Police also found evidence that Monica might have been pregnant at the time of her disappearance. At this point, Brian began to appear increasingly more suspicious. Those suspicions grew after investigators searched their home and found evidence of a "crime-scene clean-up" on their kitchen floor. Tiles from the floor were removed, and investigators were able to determine that a large amount of human blood had been present in the cracks between the tiles. That blood was later confirmed to belong to Monica. From that point forward, authorities began to investigate Monica's case as a murder. Brian and his ex-wife Jarlyn Sluss were named as persons of interest, but initially no arrests were made.
Months later, in May 2020, Brian was finally arrested and charged with Monica's murder. Just days later, Jarlyn was arrested and charged with obstruction of justice and accessory to murder after-the-fact. Authorities said that Jarlyn had information about Monica's disappearance for months, yet she did not make any effort to help the investigation. Instead, she opted to assist in covering for Brian.
