His wife, Jeni Buchanan who is also a photographer and the mother of the bride, took to her Facebook page to announce the death of her husband and asked people to let her grieve. She wrote:

You never know when the last time will be the last time! Tim came into my life at a time when I was broken to the core and held me up and built me into a strong person. Over the years we raised four amazing children, cared for my little brothers when they needed us the most and had even had the honor of a beautiful grandchild.
He was the most beautiful soul I have ever known and I will never be the same without him. I know he loved me and our family. I am so very grateful for this image of us that our dear friends Kelly Rae Stewart and her husband snuck during our daughter's wedding yesterday. Little did I know just a few hours later we would lose him.
****Please no phone calls right now.**** I am still in Costa Rica and on top of that I just can't deal with much right now. Once we have plans settled, someone will update or announce them. For now, just pray. He was always the one to make us feel better when things went wrong and so we need all the prayers we can get.Sheriff Bruce Bryant told PEOPLE magazine..
"All of our hearts are saddened about the loss of this great law enforcement officer. Tim dedicated almost 19 years to this profession as an outstanding Deputy, Forensics Investigator and most recently Detective in Computer Crimes. His talents will be sorely missed. Our thoughts and prayers go out to his family in this difficult time.”
