Investigators used side scan sonar to probe the depths of the Charles River Wednesday, searching for Zachary Marr, the 22-year-old man who Boston police have said was recorded on a surveillance camera disappearing into the river underneath the Zakim Bridge.

For the second straight day, the State Police Dive Team focused on the area near the locks leading to the harbor but ended the day’s search without success. The team will resume its search later in the week.

Sonar detected several large submerged objects that were investigated further, but all were logs or branches.

Authorities and Marr’s family have been searching for him since he was last seen outside the Bell in Hand Tavern near Faneuil Hall around 1:50 a.m. on Feb. 13. Police Tuesday disclosed that surveillance video appears to show him going into the river.


His father, Matthew Marr, told the Globe Tuesday that police recently told the family that the video shows Marr on a walkway and then walking on train tracks before he disappears into the water. The father said he recognized that the video appears to confirm the worst fears about his son’s fate. but he was still holding out hope.

“I just want him home. I just want to get closure,” Marr told the Globe. “I know that he probably won’t get home . . . but our floodlights will stay on anyway.”

State Police spokesman David Procopio wrote in an e-mail that divers used side scan sonar from a boat as it traveled on the Charles River underneath the Zakim.

“The sonar feeds images of the river bottom back to the boat,’’ he wrote. “If the sonar detects something that warrants further investigation, we will dive down to what the sonar has located to examine it further.’’

He said four divers were on the scene along with other personnel and that the search was in 25-foot-deep water. “We are focusing on an area of the river under the Zakim and an adjacent elevated railroad track, near the locks,’’ he wrote.
