This sound brings back too many bad memories for Linda Ives.
"Everytime I hear a train, it brings visual images."
Memories of her son Kevin Ives and his friend Don Henry.
"They were never given a fair investigation of their murders."
According to officials, it was not a murder.
All agree the boys were found dead on the railroad tracks between Alexander and Shobe.
Officials say they had been hit and killed by the train.
The parents believe there was more to it than that.
So Kevin's mom had the bodies exhumed, and a second autopsy performed.
The pathologist that did the second autopsy says very firmly that signs of murder were clear.
Ives says the report revealed Kevin had received a crushing blow to the head.
And Don had received stab wounds to his back.
It was the opinion of that pathologist that the boys had been killed before the train passed.
"I believe the coverup of the murder started that night, immediately."
Both the boys parents say they just happen to be in the wrong place at the wrong time.
And want more answers to close this case.
"I want an active and thorough investigation.
Curtis Henry says, "I would like for them to reopen it.
A balloon release at Alexander Park in honor of the boys marked the anniversary.
"We're so thrilled that the City of Alexander has chosen to honor them."
The ceremony included the dedication of a bench that will forever remember the good times of Don and Kevin.
Families hoping one day the good memories will outweigh the bad.
