Atcha Noopathum, who worked at the same shop as a garage mechanic, sustained two blunt blows to the head, which was wrapped in a black plastic bag.
The shop caretaker, identified only by his nickname Joop, got police attention when he asked for Bang Khen police's help to look for Atcha after March 6.
Police said a probe showed the victim had not left the shop on March 6.
Officers also said they found the oil drum which had been recently buried in a wood behind a restaurant on Theparak Road in Tha Raeng sub-district. The restaurant owner was reportedly linked to the construction shop staff.
Police used a backhoe to dig four metres underground and extracted the body for a post mortem on Tuesday.
By the time of the body’s discovery, Joop had disappeared with police saying they suspected romantic jealousy might have been involved.
