Sofia Mckenna, 21, went missing after a late-night outing off Groton, Connecticut, on May 27, 2018. She and 20-year-old Spencer Mugford paddled a 14-foot, mastless sailboat from UConn Avery Point toward the New London Ledge Lighthouse; social media from Spencer’s phone shows Sofia smiling at the lighthouse at 2:00 a.m. and a brief video of Spencer paddling. Between 2:05 and 2:09 a.m., seven calls were placed from Spencer’s phone to Sofia’s mother; the calls went unanswered and no voicemail was left. Neither returned for planned daytime events, and both were reported missing that evening.

The overturned sailboat was found May 28 on Truman’s Beach near Orient, New York, miles from the lighthouse. Spencer Mugford’s body was recovered June 8 about two miles south of Avery Point; his death was ruled drowning. Sofia has not been found. The investigation remains active and unresolved.

Did anyone in the area witness the pair leaving Avery Point or see Sofia after that pre-dawn excursion?
