BELFAST — With the onset of cold weather, the family of Graham Lacher, missing since June 6, is calling new attention to the case with informational rallies to be held in three cities across the state.

“We desperately need the public’s help to find our son,” said his mother, Tammy Lacher Scully of Belfast. “It feels as though this is our last chance to bring him home before winter sets in.”

Thirty-eight-year-old Lacher, who ran from Bangor’s Dorothea Dix Psychiatric Center while on a supervised walk, has not been seen since the day he disappeared. “Because we haven’t had a confirmed sighting of him, we have to consider the whole state our search area,” Scully said in a press release. Gatherings are scheduled for Bangor on Oct. 21, Augusta on Oct. 22, and Portland on Oct. 23.

Blaze orange hats will be distributed at the rallies for anyone actively looking for Lacher, who is diagnosed autistic and schizophrenic and may be hiding in the woods.

“If you’re walking wood lines or hiking trails to look for Graham, we want you to be safe and warm,” Scully said, noting that deer hunting season will be in full swing by the end of this month. Along with the hats, searchers will receive a “tip sheet” describing Lacher and telling them what to do if they think they see him.

To raise awareness in new ways, the family will distribute magnetic signs at each of the gatherings. “We have car magnets as well as workplace or school magnets to put anywhere people congregate or to be seen in passing,” Scully said.

The events are also a way to give thanks to the many supporters who have spread the word and prayed for her son’s safe return. “A lot of people have seen Graham’s art and poetry on social media and have told us how much they like it,” Scully said in the relese, “so we’ve made little keepsake photo-prints for anyone who’d like one.”

The Oct. 21 event in Bangor will be held in the snack bar atrium of the Bangor Public Library at 145 Harlow St. from 11 a.m. to 1 p.m.

The Augusta gathering on Oct. 22 will take place near the pavilion at Mill Park, 1 Water St., from 1 p.m. to 3 p.m.

The Oct. 23 event in Portland will be held from 1 p.m. to 3 p.m. near the East End Boat Launch off Cutter Street along the Eastern Promenade.

The state has issued a Silver Alert for Lacher, and a missing persons case has been filed (NCIC #M396825302). The family is offering a $2,500 reward for information leading to Lacher’s safe return. For details, go to the Facebook page Missing Graham Lacher or contact Det. Tom Valente of the Bangor Police Department at 947-7384.

Lacher has long brown hair and beard, blue eyes, black-rim prescription glasses, weighs approximately 190 pounds, and was last seen wearing dark work clothes. He is likely to run if approached, so authorities should be called and, if possible, a photo or video taken. If Lacher runs into woods, the entry point should be reported to the Maine Warden Service; he should not be pursued, as that can interfere with K-9 searches.
