Unsealed affidavit reveals what may have happened to Heidi Broussard before her death
Fieramusca stayed at Broussard's and Shane Carey's apartment until Nov. 27, the affidavit said.
On Dec. 8 or 9, Shane Carey reported that he learned Fieramusca delivered a baby girl, but said he did not see any pictures of the baby.
According to the affidavit, a person who lives at the same apartment complex Broussard lived in, had video cameras outside of his residence that captured a vehicle consistent with Fieramuca's car driving at the complex around 9 a.m. on Dec. 12, the same day Broussard and Margot Carey went missing.
One witness said that on Dec. 11 or 12, she saw an adult white woman at the apartment complex carrying a small baby and walking towards a parked car. The witness reportedly told police she then saw another woman exit the car and greet the woman carrying the baby. The two women and baby then entered the car and drove away, according to the affidavit.
On Dec. 19, the witness was presented with a photo lineup that Fieramusca was in. Police said the witness was 60% to 70% positive that the woman she saw in the front seat of the vehicle at the apartment complex was Fieramusca.
Upon further investigation, officials found that Fieramusca conducted suspicious internet searches.
Police said Fieramusca reportedly searched for "reasons for Amber Alert" and "Amber alert issued Austin" on Dec. 12.
A full review of searches between Nov. 11 and Dec. 18 revealed that some form of "Heidi Broussard" was searched at least 162 times from a device using an account that lists Fieramusca's name.
On Dec. 14, Fieramusca allegedly searched "bodies found in Austin Texas."
According to the affidavit, data from T-Mobile revealed that Fieramusca's phone was in the Austin area near Broussard and Shane Carey's apartment on Dec. 12.
Authorities then began doing surveillance on the Houston-area home where Fieramusca was living. Officials said they found her car parked in a way that appeared to be an attempt to hide it.
