WEST HARTFORD — A memorial service being planned for a Connecticut woman lost at sea when her son's fishing boat sank is the center of a family controversy.

Nathan Carman, who survived the Sept. 18 boat sinking, is planning a memorial service Wednesday morning at St. Thomas the Apostle Church in West Hartford, the Hartford Courant reports.

But a lawyer representing Linda Carman's three sisters tells the Associated Press they and others aren't involved in the memorial. They say it's "premature and inappropriate" while there's an ongoing investigation into the incident.

Nathan Carman's attorney Hubert Santos said his 22-year old client hasn't given up hope his mother will be found, but believes it's an "appropriate time to begin the mourning process" since the Coast Guard ceased searching for his 54-year old mother last month.
