AP) — A judge has refused to order the release of the name of a tipster whose information led to arrests in the death of a Wichita South High School football player.

The anonymous tipster collected a $1,000 reward for information leading to the arrests in the May 1 shooting death of 19-year-old Jordan Turner. Crime Stoppers received the tip the next day after Turner’s body had been identified.

Four suspects were arrested. Three are charged with murder and conspiracy to commit murder.

A lawyer for one of the defendants wanted to learn who provided the tip.

The  Sedgwick County judge said Friday he saw no evidence authorities know the tipster’s name, and he didn’t know the tipster’s identity was essential to the defense.
