Days after Derek Sink’s body was discovered in a Planet Fitness tanning bed, his mom Karen Wetzel shared more about her son and what may have led up to the moments before his death.

On Monday morning – just hours after the Planet Fitness on Hardegan Street opened for the day – officers were called to a report of a body inside a tanning bed at the gym. Gym-goer Elizabeth Len revealed she had gone to the Planet Fitness that morning and noticed a “foul smell” which seemed to get stronger near the tanning rooms.

The body found inside a tanning bed at an Indianapolis Planet Fitness on Monday has been identified as Derek Sink, People reports. The 39-year-old’s family reported him missing on Nov. 10, an estimated two days after he arrived at the gym.
