Baby Margot cried throughout the funeral of her mother Heidi Broussard who police believe was kidnapped by her best friend then killed because she wanted the baby.

The service for Broussard, 33, was held at Johnson Funeral Home in Louisiana on Saturday, and baby Margot's crying and fussing could be heard as dozens of loved ones said goodbye to the woman described as a 'star in the middle of darkness' and the 'perfect mother'.

Balloons were released following the procession to the cemetery, a day after Broussard's fiancé Shane Carey was seen attending a visitation with the late mother's six-year-old son Silas and a woman who cradled Margot.

Authorities say suspect Magen Fieramusca kidnapped the infant alongside Lake Charles woman Broussard who was found strangled in the trunk of a car December 19. Margot, who was born on November 26, was found unharmed a week after they went missing.

On Saturday, Broussard's youth pastor officiated the ceremony where guests sang Hallelujah by candlelight.

'We'll get up every day and remember her and, like she said, let her legacy live on and do our best to make sure the kids know how wonderful she was,' Broussard's childhood friend, Rebekah Guillory, told KVUE.

'Having to go through this process, we just never imagined that something like this would happen.'

The childhood friend added: 'She chose to be happy. No matter what was going on, she'd always act like, "You know what? It's going to work out." Don't sweat the small stuff. Heidi didn't. She loved deeply. Love the same.'

Guillory's sister Rachel Powell added: 'Every fiber of her being was wrapped around in her children.'

Powell told CBS Austin: 'She had that kind of charisma about her. She walked into a room, and she would just light up the room.

'Heidi would want to be remembered as that person who loved so many people and people loved her. To know that someone could hurt someone so loving, it hurts.'

Margot was returned to Broussard's partner Carey, at his father Ty's house near Austin on Monday night, after Houston CPS dropped its application to take temporary custody.

Last week DailyMail.com revealed that Broussard repeatedly tried to leave Carey and accused him of physically assaulting her.

Her friend, Cliff Nolte, showed photos she sent him evidencing injuries she suffered after her fiancé allegedly attacked her in a row over her planning to split with him.

Bruises to her arms and legs can clearly be seen in the pictures which Broussard sent to her friend of 20 years Nolte, 37.

In the social media messages that accompanied the photos, Broussard said the bruises were due to Carey 'grabbing' her.

No record of police call outs to Broussard's home could be found and Carey has no publicly recorded convictions.

Cops arrested Fieramusca, in connection with Broussard's death, and charged her with two counts of kidnapping and one count of tampering with a corpse.

Police sources say another unnamed individual was also arrested in connection with the case.

Nobody has been charged yet with Broussard's murder.

The Austin mother's body was discovered after a tip led police to Magen's home in Houston. They found Margot alive and well inside the home.

Authorities say Fieramusca, who also goes by Megan Humphrey, pretended the baby was her own with the name 'Luna Mae'.

She had been faking her own pregnancy throughout Heidi's, with the intention of stealing her baby once she'd given birth, cops say.

Fieramusca, also 33, had set up a baby registry on Amazon with Christopher Green, who owns the house where the body and baby were found.

Fieramusca, a 33-year-old wedding planner, had known Broussard for over 20 years.

Broussard's co-worker at a Buda Cracker Barrel branch Vicky Medina told CBS Austin: 'I knew how much she adored her family, so that has been the toughest of it all.

'It's going to be a very big void, on behalf of all of her coworkers and the community, because she was there for so long, and I think that it'll be a while before everybody heals and continues on.'

Fieramusca is set to appear in court on January 2.
