A homeless man from California was found dead in the back of a van in the early morning hours of Dec. 29 in the parking lot of Walmart in Kalispell. 

Walmart employees called in the van after it had been parked for an extended period of time and they noticed there weren't any tracks around it as they removed snow from the parking lot. Upon closer approach to the vehicle, they saw the body.

According to Flathead County Sheriff Chuck Curry, 61-year-old David Martinez appeared to have been living in the van and died of natural causes. The official cause of death will not be known until the toxicology report is returned from the state crime lab, which Curry said can take weeks. 

Curry added he was unsure how long the man had been deceased before he was found but said it probably occurred several days before, most likely around Christmas.
