## Disappearance and death

On May 19, 2025 Mathis was declared a missing person after her four-year-old son, Jude, was found alone in Mathis's rented boat at Silverwood Lake,a reservoir in the San Bernardino County, California. Mathis had announced by a live on Instagram at about 2:00 p.m. PDT that Jude had been wanting to go on a boat ride for ages and this was her present to him, after 4 hours at 7pm PDT when the boats rental was over for the day and did not return, people where getting ready to set out of the direction of the boat when they last saw it. After 3 members of staff went out they eventually saw the boat drifting on its own with at the time now sign of anyone of there, as they got closer they saw a small figure laying down asleep with a life jacket on, which soon was confirmed to be Jude Mathis's son along with along with Mathis's identification which included her purse, Driving License and ATM Card. Jude told investigators that they both went swimming for a while and it started to get windy to which his mother had helped him climb back into the boat, but unfortunately she was unable to climb back onboard herself. He said he also remembers Mathis telling him to sleep and she will see him on the other side by the time he wakes up and the boat started to drift off and he finally saw her disappeared underwater before coming back up now and again. He stated that his mother was wearing a life jacket but it did not help. Mathis's vehicle, a black Mercedes G-AMG, was found in the parking lot of Silverwood Lake which was a little further away than the actual lake but it was confirmed to be her car.

The lake was closed to the public with boats and dive teams taking part in the search. On the 20th May 2025 the San Bernardino County Sheriff's Department confirmed to CNN that Mathis was presumed dead and it has now changed from a rescue search to a recovery search. The Sheriff's Department efforts did confirm that it was very unlikely that Mathis made it back to shore by the lack of evidence from her son Jude he told them that he saw her go under water several times before coming back up and then finally disappearing underwater this led them to change the search to recovery.

On the morning of the 25th May 2025 a body was found by the search team floating in the water of Silverwood Lake which was confirmed by the San Bernardino County Sheriff's Department the identity wasn't revealed but the sheriff of San Bernardino County Sheriff's Department did say that it is possibly the body of Mathis. At 2pm on 25 July 2025 the San Bernardino County Sheriff's Department confirmed that the body was of Mathis this was confirmed by dental records by the San Bernardino Health Center. The Sheriff John McMahon stated that Mathis had died on the 19th May 2025 due to drowning and they have no concern that anything else has led to her death. Sheriff McMahon suggested that Mathis and Jude who already confirmed that it was a windy and struggled to get back to the boat which was found unanchored and so may have drifted from where they entered the water. He concluded that she likely "mustered enough energy to save her son, but not enough to save herself", noting how Jude described being pushed back onto the boat by his mother. On May 25, the San Bernardino County medical examiner released an autopsy report stating that the cause of death was an accidental drowning and that there was no evidence of injury or intoxication and her death date was confirmed to be the 19 May 2025.
