Authorities Monday were investigating the death of a man whose body was found in Costa Mesa on Sunday morning.
A transient searching for recyclables found the body about 5:30 a.m. behind the Bone Adventure, a dog daycare business at 2700 Bristol St., according to California Highway Patrol Officer Anselmo Templado.
The CHP is investigating because the body was found on state property at the transition road for the Costa Mesa (55) and Corona Del Mar (73) freeways.
The body was lying against a fence line behind the business, and authorities estimate the unknown male had been dead for nine to 12 days, Templado said.
Investigators suspect it was another transient, Templado said. There were no obvious signs of foul play, trauma or self-inflicted wounds, Templado said.
Investigators were working to identify the body and determine a cause of death.
