This episode contains my favorite type of ending where the killer (or killers) try to out-smart Columbo till the end. Instead of an easy surrendering as in other cases.
The development, nonetheless, is hard to believe. Why didn't anybody hear the shot? Especially if it was made by a .45 caliber. How come the security officer kept his job? In normal circumstances, the security guard would've been fired for not watching the monitors. And why did Colombo not realize that it would've been much faster to go upstairs to get an emergency phone call instead of Justin using his truck? Well, the story could've been more realistic, but I still recommend it for entertainment.
