No Trace of Missing Executive : Disappearance: Wife makes tearful plea for return of Rowland Snowdon, who was last seen Tuesday morning at Irvine bank.

After 27 years of marriage, Rowland “Rod” and Cheryl Snowdon have established a pattern: When he isn’t home, he calls his wife at least three times a day.

Tuesday, he only called once, in the morning. No one has heard from him since.

While preparing for the worst, Cheryl Snowdon, 48, appealed to the public for help in solving the mysterious disappearance and offered an unspecified reward for information.

“Please search your heart, and if someone has Rod, please, please, return him to us,” she said at a press conference, her eyes welling with tears. “He’s our life.”

Irvine police who are investigating said the Huntington Beach man’s disappearance is “suspicious.” But they have no further clues, said detective Larry Montgomery.

Police believe Snowdon was last seen at 9:30 a.m. at a Union Bank branch at 2001 Michelson Drive in Irvine near John Wayne Airport. A business director with Parker-Hannifin Corp. Snowdon, also 48, was en route to a meeting at the company’s facility on Jamboree Road, a few miles away. Records and a videotape provided by the bank show that he made a $4,900 cash deposit.

A son, Rick Snowdon, had given him the cash several days earlier as repayment of a loan.

“If he left on his own, why would he make a large deposit in our joint account?” Cheryl Snowdon asked, rejecting the possibility that her husband disappeared voluntarily. “Rod would never ever put us in one moment of worrying about where he was.”

Her husband, she fears, has met with foul play, and she is clinging to what she acknowledged is a tenuous hope that he is still alive.

“I guess as the hours go on, I can’t think of a reason . . . as to why (if he were robbed, anyone) would keep him alive,” Cheryl Snowdon said. “I guess (talking about his disappearance) is my way of coping. I am losing hope, but I try not to think about it yet.”

She was joined at a press conference Friday by two sons and other relatives. The family described Snowdon as an “ordinary” executive with nothing in his past suggesting a reason for his disappearance. He had worked for the same aerospace company for 20 years. Snowdon had a top security clearance, but his family dismissed suggestions that his disappearance could be work related.

Snowdon was described as an attentive family man who religiously called his sons at least three times weekly to chat, his wife at least three times a day to let her know his schedule and his mother every week to check on her well-being.

Tuesday, he and his wife had made plans to dine before going shopping. He called her at 8:15 a.m., his customary morning call. When she didn’t hear from him in the afternoon or later in the evening, Cheryl Snowdon became frantic and called her son, Rick, who lives in Whittier.

Rick Snowdon, 26, spent all of Tuesday night driving around the Irvine area, searching fruitlessly for his father. Thursday and Friday evening, he, his brother, 23-year-old Michael, their mother and about 60 friends and relatives returned to the bank and canvassed the area, hoping to find signs of him or his car.

“I’m desperate,” Rick Snowdon said Friday. “We’ve found nothing. At this point, I’m ready to hear anything. I just want to know anything about my father. Not knowing and not hearing from anyone is terrible for us. It’s killing my mother.”

Rod Snowdon is 6 feet tall, 195 pounds, with dark brown hair and dark brown eyes. He was wearing a light gray wool suit when last seen. He was driving a crimson 1989 Buick Electra Park Avenue, with California license 2MCU079 .

Police and family are asking that anyone who might have seen Snowdon call the Irvine Police Department at (714) 724-7000.
