A San Diego business group is trying to find out who left a box of cremated remains at a car wash after cleaning out their vehicle. Liz Greene of the Ocean Beach Mainstreet Association said the group is trying to return the ashes of Henry Efebvre, who died 17 years ago, to the person who left them behind Monday at the OB Suds car wash. Greene said the sticker on the box revealed the man’s name and the year of his death, but the information has yet to lead to any family members.
