Tim was a veteran detective with the US Sheriff's department in South Carolina. He served for 19 years and was 54 when he died.
His wife's Facebook page suggests Tim knew he was unwell but didn't go to the doctor for fear of what may be revealed about the state of his health.
Jeni explained how family was "the most important thing to him", so much so that he ignored his own health.
"He should have gone to the doctor, but he was afraid that he wouldn't be able to attend our daughter's wedding."
The family are reportedly still in Costa Rica trying to make arrangements to bring Tim home to South Carolina. A GoFundMe page has been set up by friends of the family to help cover their unforeseen expenses.
