Truitt was last seen by her roommate at their residence in Alameda, California on January 6, 2010. She has never been heard from again. On January 9, her tan 2003 Ford Ranger pickup truck with a bed liner and the California license plate number 7C23799 was found by federal park rangers at McClure's Beach at Point Reyes National Seashore in Marin County, California. Two of her dogs were inside the truck; a third was leashed to a rock nearby. Truitt, an avid hiker, has gone on many day trips to Point Reyes and is very familiar with the area. Her truck was still there the next day, which lead the rangers to begin a search for its owner. No sign of Truitt could be found in the park, however. McClure's Beach has rough water and parts of it are only safely accessed during low tide.

Truitt may have been carrying a green or black backpack at the time of her disappearance. Foul play is not suspected in her case; authorities believe she got into a mishap while hiking at the park. Truitt is a graduate of the California Culinary Academy and worked as a pastry chef in various restaurants before she injured her neck on the job and was left disabled. She took walks as a way of controlling her chronic pain, took classes in computer graphics, and taught art to children. Her body has never been found.
