A deputy was called out to the home around 2 a.m. for a report of shots fired.
Investigators say Happawana shot at the deputy, striking his patrol car. The suspect then headed back toward the home, and SWAT was called to the scene.
Authorities say Happawana grinded into a five-gallon propane tank, causing it to explode.
He then started grinding into a 500-gallon propane tank, causing a natural gas leak.
Investigators believe he was trying to blow up the home.
Around 5:20 a.m., officials say Happawana began to advance toward deputies, ultimately leading them to open fire.
"We utilized less lethal which was ineffective and, at that point, we utilized deadly force," Asst. Sheriff John Zanoni said.
Happawana died of his injuries at the home.
