Tributes are flowing in for a beloved slain musician and band teacher who was killed after a man fatally stabbed him over the weekend.

Cobb County police said 31-year-old Justin Hess fatally shot his mother, Carol Hess, several times, Saturday evening and then drove away to a storage facility in Sandy Springs.

Police said Hess then killed Bill Haynes, who rented a storage unit there, stabbing him to death simply, police believe, because Hess liked the Haynes’ car better than his own.

For years, Haynes conducted the Alpharetta City Band as they performed free concerts on July 4th and throughout the rest of the year. He also taught music at Centennial High School and then at E. Rivers Elementary School. He was also an avid tri-athlete.

Generations of students and parents, friends took to Facebook where they shared moments about how Haynes was always encouraging all those around him and how he changed the lives of young people.

"You had such a zest for life," wrote one woman.

Another wrote, "he was the kindest, (most) generous and funniest person I've known."

Justin Hess, who was arrested after a SWAT standoff, remains in the Cobb County Jail while police continue to investigate both murders. They expect to file additional charges against Hess soon.
