"The way I look at it, that's another piece of trash off the street," Pulliam allegedly told police, according to a criminal complaint.

But the 62-year-old man, in a jailhouse interview with CNN affiliate WCHS , categorically denied making that statement. He said he feared for his life when 15-year-old James Means allegedly pulled a gun on him. The complaint did not say Means had a gun.

"I mean, believe me, I did not want to kill anybody, but they're not going to kill me," Pulliam, wearing an orange jailhouse uniform, told the station on Tuesday.

Pulliam has been charged with first-degree murder in an incident police and witnesses say started with two strangers bumping into each other Monday night. He has not yet been assigned an attorney by the public defender's office.

The suspect told police he had dinner immediately after the alleged crime and then visited a female friend -- in whose home the .380 revolver used in the shooting was found, according to the criminal complaint filed in Kanawha County magistrate court.

'I felt my life was in danger'

In the jailhouse interview, Pulliam said shooting was his only option.

"I felt my life was in danger," he told the station. "I'm sorry, but I'm 62 years old. I'm not going to take a bunch of punks beating me up."

Friends of the victim told police that Pulliam and Means bumped each other outside a Dollar General store on Washington Street East in Charleston, according to the complaint.

Words were exchanged but Pulliam entered the store.

When Pulliam came back outside, one of Means' friends said, the teen and the older man again had a "verbal dispute," the complaint said.

Means crossed the street to confront Pulliam, who fired two shots at the teenager, according to the friend.

Pulliam told WCHS that he saw three teens outside a house as he was walking to the store. They were laughing, he said. One of them cursed him when he got closer.

"What the ... did you say to me?" Pulliam recalled asking the teenager.

The teen flashed a gun, Pulliam told the station. The friends encouraged Means to shoot but Pulliam continued into the store.

Pulliam said in the interview that he walked on the other side of the street when he left the store to avoid trouble but that Means approached him and taunted him with a gun.

"I just shot him," Pulliam told the station.

He added, "I work. I'm a good citizen. I don't do anything to anybody."

Pulliam said race did not factor into the confrontation. He is white, Means was black.

"I don't care if they're white or black," he told WCHS.

"Nobody is going to do me like that. It doesn't make any difference if he's black. My God, everybody I live around over there is black. I get along with all of them. Ask them."

In an email statement, the FBI said it was monitoring the case.

"If in the course of the local investigation, information comes to light of a potential federal civil rights violation, the FBI is prepared to investigate," the statement said.

Pulliam may not have had right to own gun

James Means, 15, was fatally shot Monday in Charleston, West Virginia.

It appears that Pulliam should not have been armed. He pleaded no contest to domestic violence charges in 2013, according to WCHS. Federal law prohibits anyone convicted of domestic violence charges from possessing a gun.

Means' relatives, meanwhile, remembered the teenager as smart, funny and loving.

"James could put a smile on anybody's face no matter the situation," his aunt, Teresa Means, told the station.

The teen's mother, Nafia Adkins, said: "My son's in a safer place now, and we all love him."

Obi Henderson, who knew Means from a nonprofit he founded to help young people, described the teenager as "mild-mannered."

"James means was not a gang member," Henderson told CNN Saturday. "He was not walking around in the streets trying to promote violence and wreak havoc on people. That wasn't the type of person that he was. He was an honest, humble, very respectful young man."

On Friday night, friends and relatives held a candlelight vigil for Means. And a dinner was held at Grace Bible Church.

"It was more an opportunity for us to come together, meaning family, friends ... and a time to reflect on the positive person that James Means was and give an opportunity for friends and family to laugh and embrace the joy of who he was," Henderson recalled.

The family, which has set up a GoFundMe page for funeral expenses , made a plea to Means' friends: Let justice take its course. Don't seek revenge. Don't post messages of hate on social media.

"I'm going to leave everything up to the courts to take care of this man and do whatever they have to do to make him be punished," Adkins told the WCHS.

"We don't hold a grudge, so nobody else should hold a grudge. We all have to forgive and let everything take its place."
