Brett Cummins can usually predict storms for his job as an Arkansas weatherman, but he couldn't have possibly seen this one brewing.

Cummins was questioned by police after he was found sleeping in a hot tub next to a dead, naked man detectives say was wearing a dog collar. Investigators, who have no ruled out foul play, still don't know what killed the man, identified as Dexter Williams, FoxNews.com reported.

Williams, of Mountain Pine, Ark., was found dead, naked and wearing a dog collar-style chain around his neck, Monday. Cummins, 33, believed to be Williams' friend, was sleeping next to him at the home in Maumelle, Ark., police said.

Cummins allegedly told investigators that Williams was already at the party going on there, and he did not know him.

John Barbour, the man who owns the home, told Officer Gregory Roussie that the three men -- Barbour later joined them -- began to drink and snort drugs around 11 p.m. Two hours later, Cummins and Williams went into the Jacuzzi to have a drink. Barbour told authorities he left the two men a short time later to sleep on the couch.

Around 8 a.m. the next morning, Barbour said he began cleaning up the house when he heard loud snoring coming from the hot tub. Barbour claimed he tried to wake up both men, but realized that Williams was dead.

When Cummins woke up, he reportedly screamed and was horrified. He began to vomit, Barbour told detectives.

Maumelle Police spokesman Lt. Jim Hansard told FoxNews.com that traces of blood were found in the bathtub and that authorities are considering foul play in their investigation. He also said police are awaiting the results of an autopsy and toxicology tests conducted Tuesday on Williams.

No charges have been filed.

We have not ruled out foul play, he said. This is an open investigation.

KARK 4 News in Little Rock, where Cummins works as a weatherman, posted a report of the death on its Web site Tuesday.
