PORTLAND – An 18-year-old man charged with attacking a father and daughter in a home invasion in Pittston is being held in segregation at the Cumberland County Jail.

Officials say Leo Rose Hylton was placed in segregation for his own protection after being involved in a scuffle with another inmate Friday.

Hylton, who is from Augusta, was transferred from the Kennebec County Jail, where he was being held on $1 million bail for elevated aggravated assault.

The formal complaint against Hylton says the attack early on May 27 involved “a machete, sword or knife.” Further details about the attack have not been released.

Hylton’s roommate, Dan Fortune, 20, of Augusta, is jailed on a charges connected with a November robbery at the same Pittston home, during which more than $100,000 in historic currency was stolen from a safe. Fortune has been identified by prosecutors as “a potential co-defendant.”

The victims, 48-year-old William Guerrette and his 10-year-old daughter Nicole, are continuing to recover at separate hospitals, according to a relative.

Family members said they would know the extent of injuries to the father, William Guerrette, 48, once he comes out of a drug-induced coma, while his 10-year-old daughter Nicole has regained consciousness and has spoken, said Lester Dickey of Gardiner.

“They’re still progressing,” Dickey said.

There is hope William Guerrette can be moved to the Portland hospital that’s treating Nicole so the family can remain together, said Dickey, the father-in-law of one of William Guerrette’s brothers and a member of the Church of Jesus Christ of Latter-day Saints in Farmingdale, where the Guerrettes worship.

Guerrette’s wife, 18-year-old son and another daughter also were at home during the attack but were not harmed.

The Pittston community and church have reached out to help the family. Nicole’s classmates held a bottle drive and the Guerrettes’ church organized a blood drive.

As for the Guerrettes, no one has returned to the home where the attack took place.

Dickey would be surprised if they ever return. “They’re coping,” he said. “It’s certainly a horrible thing for anybody to deal with.”
