The arrest came after the bodies of two children, a 3-year-old girl and 1-year-old boy, were found Monday morning by a farmworker at a ranch near Rosarito in Baja California, said Hiram Sanchez, Baja California’s attorney general.

The girl had been stabbed 12 times, and the boy was stabbed 17 times, he said.

A blood-stained wooden stake also was found, authorities said.

Coleman and the children had checked into a Rosarito hotel on Saturday, but video footage showed them leaving before dawn on Monday, authorities said.

The man later returned alone later that morning and then left the hotel for good, authorities said.

Coleman founded a surfing school in Santa Barbara, authorities said.

Police in Santa Barbara said Coleman’s wife had reported them missing and said she was concerned for their well-being.

Coleman could face Mexican charges of aggravated murder.

It wasn’t immediately clear whether he had an attorney who could speak on his behalf.
