Cops: Old-fashioned police work, sophisticated technology solved 32-year-old Tacoma murder
TACOMA, Wash. -- Police say DNA evidence left on a restaurant napkin was the pivotal piece of evidence they needed to solve a three-decade-old murder case of a sixth-grader that eluded them for decades. In 1986, people were stunned by the news that 12-year-old Michella Welch had been raped and killed near Puget Park in Tacoma. Michella was at the park playing with her siblings and went home to get them lunch. A short time later the siblings found Michella’s bicycle and lunch on a table but no Michella.
