Around 11:30 a.m. neighbors heard police calling out to a man named Billy Hines and asked him to come out of the house with his hands up.
Neighbors described him as a troubled man who came to the Vallejo home armed with a shotgun asking for money. They say the couple who owns the house had cared for him in the past, but they weren't home. When police arrived the man ran into the house.
"He came to the doorway with a firearm and the officers fired on him. He retreated back into the residence," said Vallejo Police Lt. Lee Horton.
While the entire block was being evacuated, police began negotiating.
"We spoke to him and he made threats to shoot and kill officers and to shoot and kill other people," said Horton.
Then around 1:00 p.m., police say the man poked a shotgun out the window and fired at them. Several officers answered with a barrage of bullets.
SKY7 HD captured images of an armored police vehicle barreling toward the home at Sutter and Indiana streets. Police ripped lattice work away from the front porch with long-handled tools.
SWAT officers found a man dead inside the home when they entered around 3:30 p.m. Police won't say how the man died, only that he had fired on them earlier in the day.
"We heard all these shots, it sounded like at least 50 to 60 shots went off," neighbor Amina Matthews said. "So we're all sprawled out on the living room floor, lying on our stomachs."
Fellow neighbor Nakida Gross added, "And they just kept shooting and they stopped and now they've evacuated everybody."
Police first went to the home after getting a report of that a man had a shotgun. Officials have not released the name of the man who died.
Police bullet casings littered the ground outside the home and more than 10 hours after it all started, there was still a crime scene.
