DANVERS (CBS) – A long line of St. John’s Prep students held hands and lined the streets of their Danvers campus in a show of respect for Pete Frates as his funeral procession passed by Friday morning. The former student of the school for boys, who went on to become a renowned advocate for ALS research, died Monday at age 34.

Bells rang as the procession made its way through the campus. All 1,700 students and faculty wore a No. 3 pin to honor Frates. He wore that number when he played baseball, hockey and football at the school.
