FLORENCE, Ariz. (AP) -- Authorities say a Casa Grande man has been arrested in a fatal 2013 shooting in Florence.
 
Pinal County Sheriff's officials say 27-year-old Andrew Matthew Salazar is being held on $100,000 bond on suspicion of second-degree murder.
 
It was unclear Friday if Salazar has an attorney yet.
 
Sheriff's officials say 27-year-old Robert DeArman, of Florence, was found dead with a single gunshot wound to the chest on Oct. 11, 2013.
 
Authorities say DeArman and three friends were drinking heavily for about five hours until the shooting.
 
A 15-month investigation by the Sheriff's Office indicated Salazar allegedly fired the weapon.
 
A county grand jury indicted Salazar on one count of second-degree murder and one count of misconduct involving weapons by a prohibited possessor. He was arrested Wednesday.
