Barreaux is credited with drawing these Dan Turner, Hollywood Detective stories. The color story is from Crime Smashers #7 (1951), and the second is originally from the pulp Spicy Detective (January, 1943), by way of the Malibu Comics reprint, Spicy Tales #1 (1988). Robert Leslie Bellem is credited as the writer. He created Dan Turner for the pulps, and was known for his overcooked dialogue like "a roscoe sneezed," and "Jeepers! Baldy's been skewered through the ticker! He's defunct!" Bellem went into writing for television after the pulps were skewered through the ticker. He did scripts for The Lone Ranger, Adventures of Superman, 77 Sunset Strip, and many more. He died in 1968.
In looking at the artwork for these Dan Turner stories I'm venturing the opinion that despite Barreaux's credit they are shop jobs. Maybe he had something to do with them, and maybe not. In "Off-stage Kill" Dan Turner is shown mostly from the back in a very static layout. The only time the story comes alive is when the girls are fighting. "The Murdered Mummy" has some of the same faults, but is much livelier in its layouts.
