Summary based on the NamUs case record (MP42184) and 5 other sources
Ronald James Coulombe, 54, was last heard from on September 25, 2017, in San Diego, California. He had made plans to visit his family in Massachusetts and had sent his son possible flight details via text message. However, when his son attempted to call him, there was no response, and no one has heard from Coulombe since that day. Described as a 5'11" Caucasian male weighing around 130 pounds, Coulombe had several tattoos, including a snake and skull on his forearm, and a tribal design on his neck.

At the time of his disappearance, there were no specific leads or significant developments regarding his case. His family, who had expected him to visit, became concerned when they could no longer reach him. The San Diego Police Department continues to investigate his disappearance.

Though missing for years, Ronald Coulombe's case remains unresolved, with his family and investigators still hoping for new information. Anyone with potential details is encouraged to contact the authorities.
