FLORENCE, AZ - The Pinal County Sheriff's Office says it will ask two Phoenix residents be charged with murder because a heat exhaustion victim has died several days after being found along with other immigrants in a truck .
Sheriff's spokesman Tim Gaffney says the office was notified early Wednesday that the victim, a man from Mexico, had died at a hospital. The victim's identity is being withheld pending notification of his family.
Gaffney says the Sheriff's Office will request a felony murder charge be filed against the driver, 25-year-old Nathan Lamb, and his passenger, 25-year-old Elizabeth Kay, both of Phoenix.
According to the Sheriff's Office, the man who died was among eight heat exhaustion victims found Sunday in the back of a truck parked at an Interstate 10 gas station northwest of Tucson.
