MONTECITO, California — A founder of a Catholic school in Ventura is among the fatalities caused by mudslides in Southern California, which have left at least 17 people dead and many others missing or injured in Montecito.

About 100 homes were destroyed and hundreds of others were severely damaged in the coastal enclave of about 9,000 people northwest of Los Angeles.

Several news accounts said that a mudslide swept Roy Rohter, who founded St. Augustine Academy in Ventura, and his wife, Theresa, from their home in Montecito early Jan. 9. Theresa was rescued and said to be in stable condition, but Roy did not survive.

“Roy’s life has been in service to his good, loving and ever-forgiving God,” said Michael Van Hecke, St. Augustine’s headmaster. “He has done so much for so many people and pro-life and Catholic education causes. … Thousands have been blessed by the Rohters’ friendship and generosity.”

Heavy rains triggered the mudslides in an area ravaged a month before by wildfires. The Associated Press described a “torrent of mud, trees and boulders that flowed down a fire-scarred mountain and slammed” into Montecito in Santa Barbara County Jan. 9.

First responders waded through waste-high mud to rescue people. Law enforcement officials said the area “looked like a World War I battlefield.”

“Roy Rohter was a man of strong faith and a great friend of Catholic education,” said Michael F. McLean, president of Thomas Aquinas College. The Rohters have been longtime benefactors of the college in Santa Paula. Their daughter, Andrea Rohter Krautmann, and her husband, Jay, are graduates of the school; the headmaster of the Ventura school also is an alumnus.

As “founder and benefactor of classical Catholic schools,” Rohter played “a pivotal role in the lives of countless young Catholic students — students who came to a deeper knowledge and love of Christ because of his vision, commitment, and generosity,” added McLean in his statement, posted on the college’s website.

The college community will greatly miss Roy’s “boundless energy and enthusiasm,” he added.
