ALBUQUERQUE (KRQE) - More information is being learned about the man police say was behind the violent day in Albuquerque.
Still, one of the biggest questions remains unanswered, why did he do this?
“We were shocked, because he was a good neighbor, he was a good friend,” Alfredo Rodriguez said.
That's how Alfredo Rodriguez describes 35-year-old Christopher Chase.
“Almost like family, you know,” Rodriguez said.
The two had been neighbors for a couple of years at this southeast Albuquerque duplex, but police describe Chase much differently.
“We do know that he has a tattoo on his body that says “cop killer,” Albuquerque Police Chief Allen Banks said.
Police say Chase is the man behind Saturday's shootout that sprawled across the city, injuring three APD officers and one Bernalillo County Sheriff's Deputy.
Police say Chase was wearing camouflage, a black mask and body armor, using an assault rifle to fire at authorities. Now, they are trying to figure out why he did it.
“We are investigating into his background right now to determine what actually caused him to go on his rampage yesterday,” Banks said.
Police made contact with Rodriguez later in the day.
“He said, “Do you know this man?” I said “Yeah, that’s my neighbor, what happened?” They showed me Chris's picture and I said “yeah.” They said, “you didn't hear the news?” I said “no.”
Chase died in the shootout. Shortly after, SWAT teams searched his home.
“The police had everything blocked,” Annabell Romero, a neighbor said. “I couldn't get in my driveway. It was very scary!”
Police say Chase has a had a few run ins with the law.
“He does have a criminal history ranging from misdemeanor to felony charges,” Banks said.
Those include parking tickets, along with embezzlement and fraud. Chase was sentenced to probation for the fraud charge.
Off-camera, his roommate called Chase a “gun fanatic,” adding that he had always been a little crazy.
Neighbors say Chase was usually pretty quiet and that he kept to himself for the most part. That roommate KRQE News 13 spoke to says he wishes things could've ended differently.
Police couldn't say for sure if chase was from Albuquerque.
Chief Banks says they're waiting on autopsy results to determine if he was killed by officer fire or if he took his own life.
