A 33-year-old woman arrested in Texas on Thursday after the discovery of the body of Heidi Broussard was close friends with the victim, a source tells PEOPLE.

Magen Fieramusca was charged Friday morning with two counts of kidnapping and one count of tampering with a corpse in connection with the Dec. 12 abduction of Broussard and her newborn daughter, Margo, according to a spokesperson from the Travis County District Attorney’s Office.

Another friend of Broussard’s, Vickie Shreves, tells PEOPLE she saw both Fieramusca and Broussard’s fiancé Shane Carey in the delivery room when Margo was born in November.

Chris Fine, whose sister is friends with the suspect, tells PEOPLE that Fieramusca called his sister, who could hear a baby calling in the background. Now, it is suspected that the baby was Margo.

Fieramusca allegedly masterminded the abductions of Broussard, 33, and her baby girl, who is just weeks old.

“She was supposedly Heidi’s friend for a long time,” says a family member of Broussard’s. “We’ve been knowing her for a long time.”

Details on Broussard’s death were not immediately available.

It was also unclear what led police to Fieramusca’s Houston-area home Thursday evening, where the baby was found alive and unharmed.

Broussard’s body was found in the trunk of a vehicle registered to Fieramusca, the prosecution spokesperson says.

DNA testing is being performed on the baby and the woman’s body to confirm they are the missing mother and child.

Broussard was last seen dropping her 6-year-old son off at Cowan Elementary School in Austin.

Fieramusca is being held on $600,000 bond, PEOPLE confirms.

Her arraignment was scheduled for Friday morning, but PEOPLE was unable to determine if she had entered a plea to the charges against her.

It was also unclear if she was represented by an attorney who could speak on her behalf.
