It's the first murder in Amarillo this year and details continue to pour in.
It happened on the 3300 block of South West 8th Street just after 10:30 Saturday night.
When police arrived, they found a man stabbed several times.
There were still some unanswered questions after we spoke exclusively with an eyewitness to the crime, so today, NewsChannel 10's Felicia Lafuente spoke with Amarillo police and went back to the murder scene to see what she could dig up:
Verbal fights, a chase, stabbing.
That's what police say lead up to the death of 39-year-old Richard McKinley.
"These two have been arguing for probably the last week or more. We don't think there's been any kind of physical confrontation prior to that night," says Lt. Gary Trupe of Amarillo Police Department's Special Crimes Unit.
The man charged with murder is 19-year-old Justin Noble.
But there is also another person who may be connected to the crime.
"There was another person involved with chasing after Mr. McKinley, we do know the identity of that person. We have spoken to him. We don't believe he was directly responsible for the homicide. We think the only one responsible is Mr. Justin Noble," says Trupe.
We're told by police and neighbors that Richard McKinely lived in a RV right next door to where Justin Noble lived.
"What contact they had on a daily basis, I don't know, what was their schedule, who was there, when did they have contact, everything. We're not done with that part yet," says Trupe.
We wanted to know more, so we went to the house where Justin lived.
We spoke with a man who would not tell us his name, but knew both the suspect and victim.
"They were both my friends... I'm sorry what happened. I don't know what caused this and I don't know what's going to happen, that's all I can say."
An autopsy is scheduled for tomorrow in Lubbock.
