As authorities scrambled to determine the cause of their deaths, part of a river near where the family was found was closed in September due to toxic algae.

Toxic or harmful algae, also known as blue-green algae, grows in warm, slow-moving, nutrient-rich waters, according to the Centers for Disease Control and Prevention (CDC). When ingested or ingested, toxic algae can cause illness or death in humans and animals.

During Thursday’s press conference, police said they did not believe the family had ingested the water in the area. They also noted that there was no filtration system with them, but an 85-ounce bottle of Camelbak water and a bottle with infant formula were found near the site.

The water inside these bottles was tested but came back toxin-free and appeared to be clean or tap water, police said.

Later in the conference, Mariposa’s public information official released a family statement that said, “The loss of a close relative is a pain that is almost beyond words. When that loss is quadrupled, and one of those losses is a baby, the pain is indescribable. “

The family went on to explain that “the lack of knowledge and certainty as the reasons for the death” caused them to frequently question the circumstances of the death during “every day and night”.

“Our hearts will never forget the good life of John, Ellen, Miju and of course, Oski,” the statement concluded. “They will stay with us wherever we are and whatever we do.”
