A man's body was found inside a home in National City after police were visiting the residence to conduct a welfare check.
Police were following up on the status of a man at 229 W 11th St. in National City when an external natural gas leak was discovered at the home. Firefighters secured the leak and the body of the resident was discovered inside the house.
Neighbors told NBC San Diego they had not seen the man since last week.
Police said there are no signs of foul play and believe the man died from a heart condition before the gas leak occurred.
