HOLLY SPRINGS, N.C. (WTVD) -- Newly unsealed warrants in the disappearance of Holly Springs mom Monica Moynan shed new light on why police believe she is dead. The warrants -- which were signed and approved in August and first obtained Oct. 14 -- show that investigators found a positive pregnancy test and interviewed a friend of Moynan who confirmed that Moynan believed she was pregnant. Investigators also learned that she made, but failed to keep, an appointment at a women's health clinic in April."We believe that Monica being pregnant may have been a factor in the incidents that led up to Monica's death," the newly unsealed warrants read.Holly Springs police officers have been actively investigating 23-year-old Moynan's disappearance since late July when her apartment manager and mother reported that they hadn't seen her in a while and were concerned for her safety.Moynan's parents Brandon and Melanie Tucker sent ABC11 this statement Monday:Police have not publicly called Moynan's death a murder. Holly Springs Police Department confirmed Monday that the case remains classified as a death investigation with suspicious circumstances.Moynan's ex-boyfriend is now being called a person of interest in the case. Investigators believe he has key information regarding her death.Police also searched the home of Moynan's ex-boyfriend's ex-wife. Police monitored their communication and, according to one warrant, she asked him if police would ever find Moynan, to which he responded, "no."Authorities said the ex-wife also admitted to pretending to be Moynan in a call to apartment management.She has not been named a person of interest.Previously released search warrants showed that Moynan's ex-boyfriend had been driving around in her car and pretending to be Moynan in text messages to her family.He told police he was using the car to transport their children, since it was the one that had the car seats.

He said he was trying to help her kick the habit, but she eventually texted him saying she couldn't do it anymore and he'd not heard from her since.Moynan's mom told police that her ex-boyfriend was abusive and a habitual liar. She said her daughter was trying to build a great life for herself and her children, but that her ex-boyfriend continued to stalk her.Moynan's ex-boyfriend has a history of assault cases against him. Moynan had also taken out a Domestic Violence Protection Order against him.Anyone with information is asked to contact Detective Mitchell Ham of the Holly Springs Police Department at (919) 567-4702.
