The baby was just 4 months old, and was left unattended inside a hot parked car at an apartment complex in San Diego's El Cajon area.

Police received an emergency phone call and attended the Belle Vista Apartments in the 500 block of north Mollison Avenue around 1:30 p.m. to investigate. They found the child in the car, and he was unresponsive.

The baby was given CPR at the scene and then rushed to Grossmont Hospital, but he later died, police have confirmed.

The alarm was raised after a group of local neighborhood children saw the baby left alone inside the car. They alerted another local resident, Larry Singleton, who has since said, "It's hurts me to know that someone's baby passed away. It's really sad."

Singleton confirmed to reporters that he did not know the baby's parents, but that they had only just recently moved into the apartment complex.

When the baby was found in the car it was 80 degrees Fahrenheit in El Cajon on Saturday.

Police have questioned witnesses to the incident and have been collecting evidence, and the parents of the child were questioned on Saturday afternoon. However, by Sunday morning officials reported that the parents had been arrested, and were believed to be responsible for the baby's death.

In 2012 there were 33 deaths due to children being left inside cars, according to the Department of Geosciences at San Francisco University, which conducted a study into the tragedies. So far this year there have been a further 33 deaths from children being left unattended in hot cars.

A county medical examiner is now investigating and will determine the exact cause of death of the baby.
