The State Police dive team searched the waters for a second consecutive day in the hopes of finding information about a missing Harvard man.
Wednesday afternoon, the dive teams concluded their search of the Charles River under the Zakim Bridge, near the locks leading to the harbor.
Police are searching for Zachary Marr, a Harvard resident who went missing on Feb. 13 after leaving the Bell In Hand bar.
The dive teams used sonar during their search, which detected several large, submerged objects that were then investigated further by divers.
All of the objects turned out to be logs and branches.
The State Police dive teams will resume its search of that area later this week.
