NASHVILLE (AP) - A bill that would require working carbon monoxide detectors in leased recreational vehicles has been named after five people who died from carbon monoxide poisoning last year at a bike rally in Clarksville.

The bill, sponsored by Rep. Joe Pitts of Clarksville, was advanced in a House subcommittee on Tuesday. Christine and Ed Watson, both of Clarksville, showed a picture of their daughter, Kathryn Over, and her husband, Jonathan, who were among the five killed last September during a Bikers Who Care event.

"It would add a provision to lease agreements that would give the lessee and the lessor comfort that the carbon monoxide detector in those RVs had been tested and were in working order," Pitts said.

He amended the bill to be called the BWC 5, after the Bikers Who Care organization. The bill would also allow for court costs and attorney's fees to be included as damages in civil suits stemming from failure to comply wi th this requirement.

Police said the deaths were accidental after a generator was found near a vent for the trailer and all the windows and doors were shut. The victims were attending a festival that the bikers group stages annually to raise money for needy children.

In addition to the Overs, who were both 27, James Franklin Wall II, 38, Timothy Bryan Stone, 39, and Allison Elizabeth Bagwell-Wyatt, 32, were also found dead in the RV.

Clarksville police said that the medical examiner found carbon monoxide saturation levels of 45 percent or more in their blood. There was not a working carbon monoxide detector in the RV, which had been rented from nearby Fort Campbell, Ky., for the event.

The law's requirement of a working detector would not apply RVs rented in other states and brought into Tennessee, but relatives of the victims said they believe it will prevent other families from going through the kind of tragedy they faced.

"It would mean that f uture generations would not have to go through the heartache that we have been through since September," said Christine Watson. The couple had two twin sons, who now only know their parents through pictures.

"It's hard," she said. "They see momma and daddy's picture on the wall."

Not being campers themselves, Ed Watson said he was surprised that rented RVs were not required to have working carbon monoxide detectors. But they said the community of Clarksville and the Bikers Who Care organization has supported the families since the tragic accident.

"The whole entire community of Clarksville has opened their hearts to the twins and all the children," Christine Watson said.
