McQueen was arrested on suspicion of first-degree murder and was
taken to county jail in Martinez, where he is being held on $1 million bail.
His arrest came weeks after he allegedly shot and killed Callen,
who was found suffering from a gunshot wound at a home in the 2600 block of
Cornelius Drive in Tara Hills, according to Lee.
Anyone with additional information about the homicide is asked to
