STEWARTSTOWN, N.H. - Authorities said they have knocked on 300 doors in this area so far looking for missing 11-year-old Celina Cass and will install a new cellphone tower to improve communications among the forces involved in the search.
Cass was last seen Monday night in her home in Stewartstown, a mile from the Canadian border. Jane Young, of the New Hampshire attorney general’s office, said yesterday that investigators are following up on about 225 tips and will continue searching by air and on foot.
A dog trained to search in water also was used. Across the state line, detectives were going door-to-door in Canaan, Vt., yesterday, while others searched fields and a nearby lake.
“We simply don’t have a lot of answers in this case,’’ Young said.
FBI agent Kieran Ramsey said tips have come from as far away as North Carolina and Illinois. A new poster was distributed with several photos of Cass.
A statement from Cass’s relatives urged anyone with any information about her disappearance to come forward.
The family had their own message for her: “If you can hear this now, please know how much we love and we miss you. You are in our thoughts and in our prayers. We will not stop searching for you until you are back in our arms.’’
Police have said there is no indication Cass ran away or that someone took her, though members of an FBI team that specializes in child abductions are working on the case.
Shannon Towle, who runs a convenience store across the street from Cass’s home, said residents are not giving up hope.
“We’re going to have a vigil every night until we get her home,’’ she said.
Cass is 5 feet 5 inches tall, weighs about 95 pounds, and has hazel eyes and waist-length brown hair.
