Dave Cantin was also swept to his death in the mudslide
David Cantin, 49, died after being swept away from his home along with his teenage son. His daughter Lauren was filmed being rescued by firefighters from their home after they heard her screaming from the wreckage.
Friends initially reported that his son Jack, 16, had been found safe and was hospitalized but those reports lost weight on Thursday as relatives continued to search for him.
Daughter, Lauren, 14, became the face of survival when rescuers pulled the mud-covered girl from her flattened home earlier this week
NeoTract, a maker of devices used in the medical field of urology, launched a fundraising page Wednesday, asking for financial support for the family of Cantin's mother, Kim, a marketing executive.
In two days it more than tripled its goal of $20,000. It took firefighters hours to dig Lauren out of the mud that destroyed her home.
'I thought I was dead for a minute,' she told them before an ambulance took her away.
David was vice president of global sales for a leading developer of instruments used by surgeons.
Cantin's company, NDS Surgical Imaging, developed some of the medical industry's earliest digital imaging technologies for minimally invasive surgery.
He graduated from Bryant University and obtained a graduate degree from Xavier University, according to his employer's website.
He was also a Scoutmaster for the Boy Scouts.
