Mystery as newborn found dead inside fast food restaurant bathroom with police searching for woman in surveillance video

MYSTERY surrounds the discovery of a newborn's body after the infant was found dead in a fast food restaurant bathroom.

The remains of the baby boy were found at a McDonald's around 2pm on Sunday, according to the Phoenix Police Department.

Police responded to the restaurant after getting a call about someone hurt and found the infant.

Despite life-saving efforts on the baby, he was pronounced dead at the scene.

The results of an autopsy are still pending.

Police released surveillance footage of an unidentified woman in a black Calvin Klein T-shirt leaving the bathroom before the baby's remains were found.

It's unclear if she is connected to the investigation, but the police department posted the video on social media and asked anyone who recognized her to call authorities.

An investigation into the infant's death was ongoing, and no further updates were released as of Tuesday night.

ANOTHER NEWBORN FOUND

Another investigation unfolded in Connecticut last week after a newborn was abandoned on the hood of a car.

Police got a 911 call around 4.15pm on March 23 from a woman who described seeing a man place an infant on the hood of a parked car, 

State troopers said the infant was transported to an area hospital where it was determined to be a 28- to 30-week-old premature newborn.

The baby was listed in stable condition.

Officials with the Eastern District Major Crime division launched an investigation to find the man who was seen prior to police finding the infant.
