The partially clothed bodies of a man and woman were found inside the cab of an idling 18-wheeler at a Southeast Side truck stop Wednesday.
The bodies were so badly decomposed that investigators couldn't immediately determine a cause of death. The Bexar County medical examiner's office will conduct an autopsy today.
There were no indications of foul play, Sgt. Tom White said, noting, "there were no obvious signs of trauma."
Two truckers at the Petro Stopping Center in the 1100 block of Ackerman Road, close to Interstate 10, noticed a foul smell coming from the neighboring truck around 2 p.m. and alerted managers, who called police.
The truck had been idling next to theirs since they arrived at the truck stop Saturday, they said. It's not unusual for truckers to leave their vehicles on while they're resting to allow the air conditioning to work.
The truckers said they hadn't seen the couple except for shortly after they arrived, when they noticed the outline of a figure getting inside the truck.
