Trapped and dying in desert, David Welch leaves behind love notes -- and questions

(CNN) -- David Welch hopped into his maroon Pontiac Montana van last month and drove for hours. Without saying where he was going, he kept on driving, police say.

Nearly seven weeks later, a hitchhiker found him in a deep, isolated desert patch in Utah, hundreds of miles from his Kansas home.

Injured and trapped in his car, he'd spent his final days penning love letters to his wife of 32 years and four sons.more
