Man bursts into flames after being shot by a taser gun Last updated at 13:56pm on 20th June 2007 Comments Comments Police are investigating the firey death of a man who burst into flames after dousing himself in petrol and then being shot with a taser gun. Officers used the gun after the man had poured gasoline over himself. Juan Flores Lopez, 47, died on Tuesday at a hospital in Texas. Police initially used pepper spray when they tried to take Lopez into custody. Then they used the Taser. Some stun guns emit an electric spark when they deliver the jolt of electricity. The Texas Rangers were also investigating whether a lighter that was on the porch could have contributed to the fire. "We don't know what ignited the fire," police said. No one else was injured in the confrontation. It was unclear whether Lopez had been charged with anything. Two of his sons who live nearby said their father had been threatening for months to burn himself and his house. His wife was seeking a divorce and he did not want to have to leave the house, the sons said.
