The state fire marshal said his office is waiting for lab results on evidence from the scene of a deadly Dec. 9 fire in Bristol.
Fire Marshal Joseph Thomas said the wait time for results is currently about four weeks.
Lynn Ring, 69, died in the garage fire at the 16 Oceanside Lane home she shared with her husband, John Ring. John Ring sustained burns to his hands.
The fire, the second in two years at the same address, destroyed the garage and a Mercedes Benz convertible and caused limited damage to the home.
