The wife of a critically missing Plano man is calling for new leads nearly three weeks after he first disappeared.
Plano police believe 47-year-old Chris Tennyson walked away from his family's home on April 4. He was not carrying his cell phone, wallet, keys or, most critically, his medication.
Tennyson's wife, Faith, said her husband's health problems include a seizure disorder.
An episode can leave him dazed and confused and unsure of who or where he is.
Faith Tennyson fears her husband is wandering, and possibly may appear homeless.
"So many people are saying it's time to get on with my life and go back to a routine, and I can't," she said, wiping tears. "If he left on his own accord, that'd be one thing. But if he's sick and just wandering, I can't do that!"
Family and friends have been calling local hospitals daily, as well as checking in with homeless shelters and passing out thousands of fliers.
They've also used dog search teams and worked with Texas Equusearch, a volunteer team.
Despite their efforts, they've found few clues.
Faith Tennyson said the majority of their leads have led back to East Plano's Haggard Park.
She also believes her husband may be riding Dallas Area Rapid Transit lines.
Chris Tennyson is approximately five-feet, eight-inches tall and about 180 pounds, with blonde hair and blue eyes. He has a large yellow tiger tattoo on his right calf.
Anyone with information is asked to call Plano police immediately.
