HARVEY, La. -- The man who police say?fatally shot ex-NFL player Joe McKnight?during a road rage dispute was jailed on a manslaughter charge as a sheriff angrily defended the investigation Tuesday, saying authorities strategically waited for days to make the arrest because they needed to find independent witnesses.Ronald Gasser, 54, was initially taken into custody after the shooting on Thursday, but he was released?without being charged, drawing heated criticism from protesters who said race played a role in the investigation. Gasser, who is white, was arrested late Monday. McKnight was black.Jefferson Parish Sheriff Newell Normand pounded on a podium during a news conference explaining the investigation.This isnt about race. Not a single witness has said ... one racial slur was uttered, the sheriff said.The case comes at a time of intense scrutiny in the African-American community about the shootings of black men, in particular by police. While this case doesnt involve a police shooting, it has drawn protests at the sheriffs department.Its not clear whether Gasser has an attorney. Attempts to reach Gassers family were unsuccessful Tuesday.The sheriff said the dispute between the men started on a bridge and proceeded into a New Orleans suburb, with both men driving erratically and yelling at each other. Eventually, the cars came to a stop and McKnight confronted Gasser, who was still seated in his car, the sheriff said. Gasser pulled out a gun and shot McKnight three times, killing him. When deputies arrived, the sheriff said Gasser handed them his gun and said he shot McKnight, 28.The sheriff said McKnight did have a gun in his vehicle but no evidence suggested he insinuated anything about it. It was his stepfathers gun and his stepfathers vehicle.During the news conference, the sheriff read aloud some of the derogatory remarks about the investigation, including racially charged comments.We have sometimes unrealistic expectations of how these things work ... you dont just run out and start slapping cuffs on people, Normand said.He noted that on Thursday, Gasser gave authorities a statement that included him being fearful and defending himself, saying that McKnight had made threatening comments. At that point, authorities hadnt interviewed any independent witnesses. One person they had talked to lied to authorities about what happened, the sheriff said.Normand said that had an arrest been made Thursday, he was certain people would be afraid to come forward. Instead, authorities identified more than 250 people they wanted to talk to by identifying license plates in the area at the time, and conducted more than 160 interviews. The sheriff said several witnesses were the key to making the arrest and made comments contradicting Gassers statements.He also pointed out that Gasser didnt ask for an attorney but instead sat with authorities for over 10 hours of interviews in the days after the shooting and gave permission for them to search his home.Normand also pushed back against questions about whether he understood the fear that a shooting like this had brought about among some in the black community.Lets not try to make this out to be something that it is not. What we had were two adult males engaged in unacceptable behavior that did not understand how to deal with conflict resolution, he said.The sheriff did not want to go into details about why he felt Gasser should be arrested even though the state has a version of the stand your ground law.Louisianas law holds that people dont have a duty to retreat and can meet force with force if they reasonably believe that using deadly force is necessary.Law experts say its not a blanket excuse.When you use lethal force, its got to be proportional, Ken Levy, an associate professor who teaches criminal law at LSU Law Center, told The Associated Press. And the only way its proportional is if McKnight was threatening serious bodily injury or death.McKnight played three seasons for the New York Jets and one with the Kansas City Chiefs.The Jets held a moment of silence Monday night before their game against the Indianapolis Colts at MetLife Stadium to honor the former running back.McKnight was rated the nations No. 1 running back recruit when he signed with the University of Southern California. He was a fourth-round draft pick of the Jets in 2010 and played three seasons for New York. McKnight had a 107-yard kickoff return for a touchdown in 2011, and it remains the longest play in Jets history.He also spent a season with Kansas City, and most recently played for the Saskatchewan Roughriders of the Canadian Football League.A decade ago, Gasser was involved in a similar altercation -- at the same intersection -- with a driver. The sheriff said that in February 2006, a man observed a truck driving erratically and called a number on the truck, speaking to a man later identified as Gasser.Gasser and the man got into a fight on the phone and then Gasser followed the man to a service station, confronted him and hit him several times. Gasser drove away, and the victim called 911.Investigators found Gasser and issued a misdemeanor summons for simple battery, which was later dismissed. Authorities have said they are trying to determine why it was dismissed. Alexandre Lacazette Arsenal Jersey . 8 Iowa State on Saturday, sending the Cyclones to their third consecutive loss.

General manager David Poile announced the move Tuesday just hours after the Predators confirmed Horacheks firing in a statement posted on the franchises website. Housley played 21 NHL seasons with eight different teams, and he just coached the United States to a gold medal at the World Junior Championships. "Phil brings a unique skill set to our coaching staff," Poile said in a statement. "He was one of the most talented offensive defencemen to play in the NHL, and he has worked extensively with young players during his coaching career. He will continue to focus his efforts on our young defencemen and assisting on the power play." Housley, 49, ranks fourth all-time among defencemen with 1,232 points as a seven-time All Star. He also was an assistant coach for the United States at the World Championships where the Americans took home bronze for their first medal at the tournament in nine years.dddddddddddd "A coach with history as a defenceman who was offensively gifted and excelled on the power play is something we have never had on our coaching staff," coach Barry Trotz said. "His insight and viewpoint will bring a fresh perspective to our team." The hiring comes after Horachek reportedly was fired Monday night, though the Predators would not comment. They finally confirmed Horacheks firing Tuesday posting a statement on the teams website. Poile thanked Horachek for his contributions on the website, but the GM said in a short statement they made the "difficult decision" to allow Horachek to pursue other opportunities. Horachek had been with the Predators since June 2003, and he interviewed for Dallas head coaching job in 2011. With Nashville, he helped develop the Predators draft picks and worked with the power play and the penalty kill. But the Predators went 16-23-9 for their first season below .500 since 2002-03. ' ' '
