HARRISBURG, Pa. (AP) -

The sister of a man whose suspected killer was arrested 33 years after the slaying says she never gave up on the case.

Valerie Waller said Tuesday that, just last year, she had asked Harrisburg's mayor for help in capturing the killer of her brother, Thomas.

Waller said  the suspect, Joseph Lewis Miller, killed her brother in 1981 after an argument. An arrest warrant was issued for Miller after he'd fled.

U.S. marshals say the 78-year-old Miller was found Monday living under an alias and serving as a church deacon in Texas.
    
Valerie Waller said she was in line to buy groceries when her nephew called to tell her about the capture. She said she broke down crying and told the concerned register clerk that they were "happy tears."
