Ten months after she took over the top job at the Santa Cruz Sentinel, publisher Molly Evans leaving to become advertising manager at the Times Herald-Record in Middletown, N.Y., the Sentinel reported today. Both papers are owned by Dow Jones & Co., publisher of the Wall Street Journal. Dow Jones is attempting to sell the Sentinel but will keep the Middletown paper. Evans said she’d rather stay with Dow Jones than take her chances with a new buyer. “Since this isn’t my home, I didn’t want to be marooned out here,” said Evans, who came to Santa Cruz from Cape Cod and has family in Connecticut. She said her family is longing to return to the East Coast. She said that as a cancer survivor, she didn’t want to risk losing the health benefits she now has with Dow Jones. The high cost of living in Santa Cruz was also a factor in her decision.
