Bringing the search for a lost dog into the 21st Century

FINDING MARISOL
On Nov. 2, Andrew and Anindita Sempere's dog, Marisol, fled into the Middlesex Fells after being attacked by another dog. In the month since then, the couple, who met in grad school at MIT, have used modern social networking to establish a small army to search for her, but so far have failed to outsmart the primal instincts of the dog.
