The disappearances sparked a frantic search and ultimately revealed a stunning betrayal months in the making by a suspect no one could have imagined, according to a March 22 episode of Oxygen\u2019s A Plan to Kill<\/a>.\u00a0<\/p>\n Heidi Broussard and Her Daughter Margot Disappear<\/p>\n Just two weeks after Broussard and fianc\u00e9 Shane Carey welcomed daughter Margot, the pair was getting back into a regular routine.\u00a0<\/p>\n While Carey headed to work on Dec. 12, 2019, Broussard dropped off their 6-year-old son Silas at school\u2014confirmed by video surveillance images at the school\u2014then called to check in with Carey around 8:30 a.m.\u00a0<\/p>\n But when Carey came home from work that afternoon around 2:30 p.m., his fiancee and baby were gone, although the 33-year-old\u2019s car was still in the apartment parking lot with her purse and wallet inside.\u00a0<\/p>\n Carey initially believed the pair may have just gone to visit someone in the complex, but he grew concerned after he picked up his son from school and they still hadn\u2019t returned.\u00a0<\/p>\n After calling her closest friends, he reported her missing to the Austin Police around\u00a0 7:30 p.m. that night.<\/p>\n \u201cHeidi\u2019s case was different,\u201d Retired FBI Special Agent Christopher Combs explained. \u201cIt wasn\u2019t just a missing woman. It\u2019s a missing woman with a 2-week-old baby.\u201d<\/p>\n No Signs of Forced Entry in Heidi Broussard\u2019s Apartment\u00a0<\/p>\n During a search of the apartment, investigators found no signs of forced entry or a struggle.\u00a0<\/p>\n \u201cThere was nothing out of place,\u201d noted host of the Jay is for Justice podcast Jay Youngblood. \u201cThere was nothing, you know, thrown around the room. Everything was seemingly normal. They didn\u2019t find any forensic evidence that a crime had been committed there.\u201d\u00a0<\/p>\n RELATED:\u00a0Obsessive Ex Guns Down Teacher\u2019s New Fianc\u00e9 After Stalking Couple for Months<\/a><\/p>\n But they did find one troubling clue that suggested Broussard could have left against her will. Margot was diagnosed with jaundice shortly after her birth and required a special formula to treat the condition, yet it had been left behind at the apartment.<\/p>\n \u201cWhat woman takes a 2-week-old baby,\u201d Combs asked, \u201cwithout food, without diapers, without a purse?\u201d\u00a0<\/p>\n Heidi Broussard Investigation Begins<\/p>\n Investigators considered the possibility that Broussard could have been suffering from postpartum depression, but Carey insisted that hadn\u2019t been an issue for his fianc\u00e9e.\u00a0<\/p>\n As the investigation kicked off, authorities deployed what they referred to as \u201creverse 911\u201d call, where everyone within a certain geographic area was called to see if they had noticed anything suspicious, but they didn\u2019t get any tangible leads from the query.<\/p>\n Suspicion soon fell to Carey\u2014who friends said had an on-again, off-again relationship with Broussard over the years\u2014but investigators were able to rule him out after confirming he had been at work all day.\u00a0<\/p>\n \u201cShane was very helpful. He gave police his cell phone. We could see when she called him, that he had in fact talked to her,\u201d Combs said. “On Dec. 12 he had already let him search in the apartment, he had let them look at the car, so there was nothing he was holding back.\u201d<\/p>\n Friends Report Maygen Humphrey\u2019s Strange Behavior<\/p>\n Given that Margot was so vulnerable, the investigation quickly ramped up, with the\u00a0 FBI also joining the search efforts, as authorities took a closer look at everyone in her social circle.\u00a0<\/p>\n \u201cInvestigators learned that Heidi was very bubbly, very social and very outgoing,\u201d Youngblood said. \u201cShe was someone who had a lot of friends.\u201d\u00a0<\/p>\n RELATED:\u00a0Mother-Daughter Duo Murder Ex\u2019s Grandmother Before Stuffing 91-Year-Old in Trash Can<\/a><\/p>\n Authorities caught a break in the case after a witness remembered seeing a woman and her baby getting into a sedan the day Broussard disappeared.\u00a0<\/p>\n Around the same time, investigators were learning from those close to Broussard and the hospital staff that her best friend Maygen Humphrey, sometimes referred to in the media as Magen Fieramusca, had acted strangely in the delivery room, \u201caggressively\u201d taking the baby from Carey\u2019s father and acting possessive of the infant.<\/p>\n \u201cOnce we got that story of what happened in the maternity room, our behavioral analysis people right away said \u2018Hey, we really got to look at this. This could possibly be a maternal desire-type situation,\u201d Combs said. \u201cMaternal desire is a mental state where a woman has an insatiable drive to acquire a child.\u201d<\/p>\n According to Broussard\u2019s friend Kelly Budd, Broussard and Humphrey\u2014who met years earlier at church camp<\/a>\u2014had both been pregnant at the same time, even sharing the same due date.\u00a0<\/p>\n \u201cWhen Heidi introduced us, unfortunately, I got a bad vibe from Maygen,\u201d Budd remembered. \u201cI didn\u2019t like her right away but Heidi\u2019s heart was so pure. She loved everybody.\u201d<\/p>\n Evidence Trail Leads to Maygen Humphrey<\/p>\n Just weeks after Broussard had given birth, friends remembered Humphrey announcing she had given birth to a daughter named Luna around Dec. 8 or 9, yet no one had seen any photos of the baby, which triggered alarm bells for investigators. Law enforcement authorities\u00a0 also couldn\u2019t find any evidence to suggest that Humphrey had been pregnant.\u00a0<\/p>\n Cell phone records and license plate readers also put Humphrey, who lived in Houston, in Austin near Broussard\u2019s apartment the day she disappeared.\u00a0<\/p>\n RELATED: Oxygen’s A Plan to Kill Season 2 Teases “Disturbed Killers” and “Nefarious Plans”<\/a><\/p>\n With a suspect identified, the Texas Rangers were called in to conduct surveillance at Humphrey\u2019s home.\u00a0<\/p>\n Meanwhile, other investigators spoke to Humphrey\u2019s ex-boyfriend, who told them that when he returned home from a work trip on Dec. 13, Humphrey told him she\u2019d welcomed their child at a birthing center and introduced him to the baby.<\/p>\n When investigators showed him a photo of Margot, he identified the photo as the baby he believed was his.\u00a0<\/p>\n Investigators believed they had enough evidence to confront Humphrey and went to her home. Although she insisted the baby was hers, an investigator searching the property noticed a foul odor coming out of the trunk of her car and discovered Broussard\u2019s dead body<\/a> stuffed into a duffel bag. A coroner later determined she\u2019d been strangled to death.<\/p>\n \u201cWe\u2019re all angry,\u201d Budd said of the chilling betrayal. \u201cWhy Heidi? Your best friend is supposed to be the person you trust more than anybody.\u201d\u00a0<\/p>\n Where is Maygen Humphrey Now?<\/p>\n Humphrey was taken into custody and charged with capital murder, two counts of kidnapping and tampering with evidence of a human corpse. Meanwhile, Margot was taken to a hospital, where she was reunited with her grieving father. Investigators believe it had been Humphrey\u2019s plan to kill Broussard and take her baby all along<\/a>.\u00a0<\/p>\n \u201cThe idea that somebody could lie for nine months to everybody they love is ruthless,\u201d private investigator Stacey Deville said. \u201cIt\u2019s calculated. It’s evil.\u201d<\/p>\n
