COLORADO SPRINGS, COLO. -- New information has been released about a triple homicide in Colorado Springs.

One week ago 19-year-old Wayne Fix, his 16-year-old brother Aaron, and their friend, 16-year-old Austin Howse, were shot and killed on Mira Loma Circle.

Then on Saturday, the man suspected of killing the teens, 24-year-old Michael Arangio, shot and killed himself during a police standoff.

Wednesday Colorado Springs Police and the 4th Judicial District Attorney's Office announced the shootings were the result of road rage.

Authorities said there is no evidence the victims and suspect knew each other.

"As the negotiators were negotiating on Saturday, it was said a couple times 'they cut me off,'" District Attorney Dan May said. "We can not imagine that cutting somebody off results in three young people being murdered, it is just unimaginable."

Hundreds of people packed the Trinity Church of the Nazarene Wednesday to remember Austin Howse, who was going to be a junior at Doherty High School this fall.

His family and friends said they are having a hard time understanding his untimely and tragic death.

"I consider all my friends family, and that is what he was, and his loss is so sad," friend Tyler Bell said.

Bell and his friend Brian Corbitt said they are devastated by the loss of Howse.

As a tribute, the two wrote a rap song about Howse's life and death, and sang it at his funeral.

"I felt like I can not bring his life back, but maybe the one thing I can do is do what he loved and what I love, and that is rap," Bell said.

Bell also made a video of the song (warning explicit words), and posted it on YouTube.

He said it is his way of keeping his friend's memory alive.

Along with music, those who knew Howse said he loved his family, his friends, sports, and Superman.

They said the past week has been extremely difficult.

"I have some videos and pictures we took together, and in them he was making funny faces and stuff, so just looking at them makes me want to cry more," friend and classmate Janice Oh said.

Along with sadness, many of Howse's friends said they are also feeling frustrated.

They said they are having a hard time understanding why someone would kill three people over something as senseless as road rage.

"He did not do anything, he was innocent," Oh said.

Bell agreed.

"I knew for a fact, from the very first moment, that Austin was in trouble because he was in the wrong place at the wrong time," Bell said. "I know Austin, and he would not get involved in things he could not handle."

A viewing was also held Wednesday night for Wayne and Aaron Fix.

Their funeral service is scheduled for Saturday morning.
