(JTA) — The missing teenage son of Boston Globe columnist Jeff Jacoby may have been sighted in Providence, R.I., a local ABC affiliate reported.

Caleb Jacoby, 16, has been missing since midday Monday. Police believe Caleb, an 11th-grader at the Maimonides School in suburban Boston, may be a runaway.

ABC6 in Providence reported Wednesday afternoon that there have been “several reports” placing the teen in Providence on Tuesday evening. No further details were reported.

Some 200 volunteers, including friends and neighbors of the family as well as members of local Jewish groups, continued to search throughout the Boston area in a coordinated effort on Wednesday. The effort was spearheaded by the Maimonides School.

Caleb’s photo has been circulated on Facebook and Twitter.

“We are so deeply, deeply grateful for everything being done to reunite us with our beloved son Caleb,” Jeff Jacoby, who is Jewish and often writes on Jewish and Israel issues in his column, tweeted late Tuesday night.

For many years, near his oldest son’s birthday, Jacoby wrote a special column called “Letters to Caleb.”
