Jerry George, 63, was found dead around 2 a.m. only a few blocks from home.
"The police told me that he hit his head," said John Toia, George's husband of 11 years.
Toia said the coroner had not yet established a definitive cause of death, but George's wallet and cellphone were still with him when he was discovered by police, who responded to a 911 call about a man down on a street.
"They knocked on my door around 4 a.m. and said Jerry was dead," said Toia.
Local police dismissed any notion of foul play.
"The investigation is still open, but it does not appear that there was any foul play or anything suspicious," said Detective Barron Lane of the Riverside County PD.
