Savanah Soto, 18, was meant to give birth to her baby boy last week but was found dead along with boyfriend Matthew Guerra, 22, inside a car dumped in a car park in San Antonio, Texas
Devastated family members gathered in a local park to pay respects to Savanah and her unborn son. Her grandma watched the proceedings sitting by trees planted in memory of Savanah's brother who was gunned down two years before
The footage shows a dark coloured pickup truck pull up in the carpark near where the bodies were found. Then boyfriend Matthew Guerra's Kia Optima pulls up and an unknown man gets out before another can be seen appearing to wipe down the side of the car
Alarms were raised when the heavily pregnant 18-year-old Savanah Soto failed to turn up at an appointment for induced labour. Her body was found on Boxing Day along with her dead boyfriend Matthew Guerra
