Neighbors living nearby alerted police when they heard the front door of the business being forced open in the middle of the night.
Police officers arrived with the owner, and eventually found the suspect lying on a table in a glassed-in chamber used for viewings of deceased people during wakes, a local police official said from Burjassot.
"The custom here is for dead people to be dressed in suits, in nice clothes that look presentable. This guy was in everyday clothes that were wrinkled and dirty," the police official said. Department rules barred her from giving her name.
"He was trying to fake being dead, but he was breathing," the officer said.
The suspect's name was not released. Police said he had served jail time in the past for robbery.
The funeral home said it was mystified about what the man could have been after, because there were no valuables or cash inside the funeral parlor.
