HAVRE DE GRACE, MD — The search for a missing 18-year-old boater from Havre de Grace has been scaled back to include only Maryland Natural Resources Police conducting a surface search, authorities say.
Fourteen agencies have been searching along the Susquehanna River since Nov. 5 for Mark Everett Coates III after his 10-foot aluminum jon boat was found overturned near Garrett Island. The search has included vessel patrols, dive teams and aerial searches using helicopters and drones, Patch reported previously.
Coates launched his boat Wednesday around 5 p.m. at the Water Street Boat Ramp. The jon boat was found capsized early Thursday morning. Coates was last seen wearing a chartreuse long-sleeved T-shirt and blue jeans.
Ongoing search efforts will include drones and possibly side-scan sonar searches, according to WBAL.
"These efforts began Monday morning and will continue until Mark is located and recovered," the agency said in a statement.
Anyone who may have information relevant to the investigation is asked to call Maryland Natural Resources Police at 410-260-8888.
