Katherine Hammontre Sundquist went on a hike with friends and her dog, Tootsie, in a national park near San Felipe, Baja California, Mexico. Due to an injured foot, she stayed behind at a set of pools while the group continued to a waterfall. When they returned, both Katherine and Tootsie had vanished without a trace.
Katherine had injured her foot days before the hike, and shortly after starting, she told her friends her foot was hurting. She decided to stay at the first set of pools with her dog while the group continued to the waterfall.
The search for Katherine was hindered by the rugged terrain, lack of clear trails, and the absence of any trace of her or her dog. Despite extensive searches involving local authorities, the Mexican military, and volunteers, no evidence of her whereabouts was found.
Katherine had been diagnosed with cancer a year before her disappearance and had opted against further treatment. Her daughter, Desiree, believes Katherine may have resumed drinking due to her diagnosis, which could have influenced her state of mind and decisions leading up to the hike.
Theories include foul play by her husband Warren, involvement of nearby marijuana farmers, or that Katherine chose to disappear due to her cancer diagnosis. Others speculate she may have gotten lost in the wilderness, though no evidence supports any of these theories.
Tootsie’s disappearance alongside Katherine is unusual because dogs often reappear after such incidents. The absence of any trace of Tootsie, including feces or signs of a struggle, has led to questions about whether both were taken or met with foul play.
Katherine and Warren had recently broken up and reconciled. They had an argument days before the hike, and Katherine had moved her belongings out of Warren’s house temporarily. Their relationship was described as calm but with underlying tensions, particularly around Warren’s drinking habits.
The footage showed Katherine and Warren preparing for the hike. Katherine made a cryptic comment about not being found if she got bitten by a snake, which her daughter, Desiree, continues to question as a potential hidden message.
Desiree traveled to San Felipe to aid in the search, contacted authorities, and worked with local volunteers. She has also used social media to keep her mother’s story alive and continues to seek answers, despite the case being officially closed.
As of 2024, Katherine’s case remains unsolved. The investigation was closed, and despite Desiree’s efforts to reopen it, no new leads or evidence have emerged. The mystery of her disappearance continues to haunt her family and friends.
In April 2019, Katherine Hammontre Sundquist embarked on a hike with friends and her beloved dog, Tootsie, in a national park near San Felipe, Baja California, Mexico. Their destination was a picturesque waterfall. Before the hike, Katherine had injured her foot, and not long after beginning the trek, she informed her friends that her foot was hurting. She decided to stay back at the first set of pools with Tootsie while the others continued on to the waterfall. It would take the group approximately 50 minutes to reach the waterfall and return to where Katherine was waiting. However, by the time the group returned, both Kat and Tootsie had vanished. Despite extensive searches of the area, no trace of either Katherine or Tootsie has ever been found. As news of Kat’s disappearance spread, rumors began to circulate within the community of San Felipe. People pointed fingers in various directions, but more than five years later, the mystery of what happened to Katherine Hammontre Sundquist remains unsolved.
