A pregnant mother expecting her second child was shot dead by a trio of robbers as she returned home from a doctor's appointment.

Kera Teel, who was seven months pregnant, was in a car with her mother when two men walked up to the vehicle and opened fire.

Her unborn daughter, who she and husband Andrew had decided to name Kyndal Jae, was delivered at hospital but died as a result of the attack.

Teel, 19, died from multiple gunshot wounds on Tuesday morning.

Her husband, Andrew Teel, told KBMT: 'She was the happiest most full of life person I've ever met. She was a great mother and wife and loyal friend. She wasn't just my wife she was my best friend.'

The victim's mother, Mindy Morris, told 12News: 'I held her in my arms I said Kera, Kera please baby.'

'She kept saying no, please, please don't, no. And I jerked her back and he opened the door and shot at her twice.'

The distraught mother continued: 'If they wanted anything I would have given it to them except my baby.'

The Beaumont Police Department in Texas said Teel was taken to the Christus St Elizabeth Hospital, where the baby was delivered.

Police spokeswoman Haley Morrow told KBMT: 'These were completely innocent victims, and so we’re really sad about the loss of life out here.'

She said there was another aggravated robbery nearby, during which shots were fire, and officers are investigating whether that and other attacks are linked to the killing.

Officer Morrow said it is being treated as a capital murder case.

A statement released by police said: 'There are over 118,000 citizens in the City of Beaumont, someone knows these suspects.

'Do the right thing; help bring closure to this family, and justice to the people who committed this senseless act of violence.'

A GoFundMe page set up to support the family has already raised more than $5,000.
