Witness Statements
The arrest report also provides details from several witnesses about the events leading up to the stabbing.
1st Memorial HS Witness:
A member of the Memorial High School track team told police he was sitting under the Memorial High School pop-up tent with the rest of his team. The victim and the suspect were sitting nearby.
“Anthony was from Centennial High School and was sitting under the Memorial High School tent. [The victim] had told Anthony that he needed to move out from under their team’s tent and Anthony grabbed his bag, opened it and reached inside and proceeded to tell [the victim], ‘Touch me and see what happens.’ No one really thought Anthony really had any weapons in his bag and [the victim] proceeded to touch Anthony and then Anthony told [the victim] to punch him and see what happens. A short time later, [the victim] grabbed Anthony to tell him to move and Anthony pulled out what [the witness] recalled as a black knife and stabbed [the victim] once in the chest and then ran away,” the report states.
The witness did not know Anthony, but he knew he was a Centennial student.
2nd Memorial HS Witness:
Police pulled the victim’s twin brother and a second Memorial High School track team member into the locker room to take their statements because it was raining heavily by that time.
The officer who interviewed them noted that Hunter Metcalf was still hysterical and could not talk.
“I attempted to ask them both what had happened. I could not really get anything out of Hunter, but [the second witness] stated he wanted to speak. I asked him what happened, and he stated they were all sitting on the bleachers under a Memorial HS tent. When another male, who he did not know, walked over and sat under the tent. [The witness] then said [the victim] told this male that since he did not go to Memorial he had to leave the tent. [The victim] and the male went back and forth and then [the victim] stood up and pushed the male to get him out of the tent. [The witness] had said during this time of arguing, the male was reaching around in his bag he had. It was at this time the male took out a knife and stabbed [the victim] and then left the scene,” the report states.
The arrest report also identified about two dozen other student athletes from various Frisco ISD high schools and four coaches who said they witnessed the stabbing.
Crime Scene Investigation

What we know:
The victim’s family previously told FOX 4 that the fatal stabbing happened just as it was starting to rain at the track meet.
The arrest report notes that it was raining heavily by the time police and paramedics arrived at the scene and began to secure it with crime scene tape.
One officer reported moving the Memorial tent over the victim and the medics who were trying to save his life.
The officer said he also found the bloody knife in the stands and quickly took pictures of it before the rain could wash the blood away.

Another officer found a blue tarp and used it to cover the knife in an effort to preserve the evidence.
Because it was windy and raining so hard, the officer also grabbed a backpack to weigh down the tarp. He didn’t realize it was the suspect’s backpack, the report states.
The officers took cell phones from several of the witnesses.
The victim’s clothes and the suspect’s clothes were also later collected as evidence.
