Murder with Too Many Notes - S10-E13
Visible crew/equipment: When Columbo accompanies Sidney Ritter downstairs to see the elevator that goes to the roof, they are alone, but as Ritter says, "I can't think what use this could be to you," the abdomen (with hand in pocket) of a crew member, wearing a blue shirt and brown pants, is visible at the right side of the screen.

Answer: "Apparent" drowning answers your question - things are not always as they seem. Drowning could be accidental, but it could also be a murder in disguise. Moreover, the actual cause of death has not yet been determined - accident, suicide, murder, or natural cause (e.g, heart attack while swimming). Columbo would be there to investigate if anything looks unusual for it to be a mere drowning or if there is evidence or suspicion of something else.

This was just on TMZ.com's "Aaron Carter Dead at 34" (11/05/2022): "Law enforcement sources tell TMZ... homicide detectives have been dispatched to the scene but we have no information or evidence of foul play. It's standard operating procedure for homicide detectives to investigate such [drowning] death scenes."
