Authorities 'Exploring Every Avenue' As Week-Old Search For Missing Texas Mom And Her Infant Daughter Continues

Nearly a week after a Texas mother and her newborn daughter were reported missing, police have yet to identify a person of interest and the FBI has gotten involved.

Heidi Broussard, 33, and her 3-week-old daughter, Margot Carey, went missing last week, having last been seen dropping off her son at Cowan Elementary School at 7:30 a.m. on Thursday, according to a news release from the Austin Police Department. Police believe that the pair’s last known location was the Austin apartment complex where they lived, authorities said during a press conference on Tuesday.

Police have confirmed that Broussard’s fiancé and Margot’s father, Shane Carey, reported her missing after she failed to pick up their 6-year-old son from school that day, ABC Austin reports.

Shane Carey said that when he returned home from work that day at 2 p.m., Broussard and the baby were already gone, but it was when he got a call from his son’s school, reporting that no one had picked up the child, that he started to suspect that something was wrong, KNOE News reports.

“I went and picked up my son, and she wasn’t home again, so that’s whenever I called police,” he said, according to the outlet.

Broussard’s car and Margot’s things were left behind in the apartment, and nothing in their home was out of place, Carey said. Broussard’s purse and wallet was also still at home, but her cellphone was gone and has been turned off, Carey said, according to ABC Austin.

Police said on Tuesday that it’s possible that Broussard and the child left of their own accord, but it's also possible that “something nefarious [happened] or foul play [is] involved.”

No arrests have been made and no suspects have been identified. Numerous agencies are involved in the investigation, including the Austin Police Department’s Missing Persons and Special Investigations units, the Texas Department of Public Safety, and the Federal Bureau of Investigation’s Child Abduction Response Deployment Team, according to police.

“This case is unique in that we don’t have a person of interest right now,” Det. Brad Herries of the Austin Police Department told reporters. “We’re exploring every avenue that we have and every possibility and to be perfectly honest, anything is possible at this point. We’re working down every angle, trying to exclude possibilities [and] narrow that down to locate Margot and Heidi, and that’s why we need the public’s help.”

Police also confirmed that there have been previous calls regarding disturbances at Broussard’s home, but did not clarify the circumstances of those calls.

Authorities are asking that anyone who may have seen the mother and daughter, or who may have any information regarding their disappearance, contact the Austin Police Department or call 911. Police have also created a tip line specifically for any information regarding Broussard and her daughter that can be reached by dialing 512-974-5100.

Police remain optimistic about the case.

“Our assumption is that they're alive and the sooner that we can find them, the better. That's why again we ask for the community's assistance, for the public's assistance. And if you see either of them or have any information related to Margot or Heidi and their whereabouts or the circumstances surrounding their past five days, we ask that you contact the Austin Police Department,” Herries said.

Broussard’s parents have said that they do not believe that their daughter would leave on her own, according to ABC Austin.

“She would not leave her son. ... Her kids are her heartbeat,” her mother said.
