A one-year-old boy died after his mum allegedly left him trapped in a hot car while she went for lip filler. Amillio Gutierrez was found foaming at the mouth and convulsing when Maya Hernandez, 20, returned to her car.

The baby boy had a body temperature of 41.7C - the normal temperature is around 37C. Hernandez returned to the car at around 4.30pm on June 29 and Amillio, who was left in the Toyota Corolla hybrid with his two-year-old brother, was declared dead at a hospital shortly before 6pm.

Hernandez told police in California that she left the air condition on in the car while going in for the cosmetic procedure. However, investigators said the car was warm and the engine was off.

Amillio's grandmother, Katie Martinez, wrote on GoFundMe: "When his mom left him and his 2-year-old brother alone in her car, Amillio was so special; he always had a smile no matter what.

"He is loved by so many, our lives will not be the same. His brother will forever be without his best friend."

The two boys were allegedly trapped inside the car outside the Always Beautiful Med Spa in Bakersfield, California, for at least an hour and a half. They were strapped into their car seats and did not have any air conditioning.

Katie said: "They were strapped in their car seats. They couldn’t even get up to save themselves. She literally locked them in their car seats and shut their doors."

She was also shocked by Hernandez's actions, saying that "she wasn't like that." The grandma explained: "She was a really loving mom. Those boys loved her. They really loved her and they relied on her."

Hernandez reportedly asked nurse at the spa if she could bring her kids with her during the procedure. The appointment only took between 15 and 20 minutes.

The 20-year-old has been charged with involuntary manslaughter and child cruelty. She is set to appear for a preliminary hearing in court on Friday.

Katie added on the fundraiser page: "He just started walking on Thursday, and on Sunday, he gained his angel wings. I will never be the same without him.

"Amillio Gutierrez, my grandson, I will be with you again in heaven. Until we meet again, you are missed so much.’ Please help us bring him home to his brother and to our family."
