The half-brothers of missing infant Lisa Irwin were re-interviewed by authorities Thursday night on the eve of the girl’s first birthday.

A specialist from the FBI, trained in interviewing children who may be crime victims or witnesses, was brought in from Washington, D.C., to conduct separate interviews with the boys, ages 5 and 8. The interviews were videotaped and lasted a total of about two hours, a family attorney said .

“They’re done now and the family is very relieved that they won’t have to be interviewed again,” said John Picerno, one of the attorneys representing Lisa’s parents, Deborah Bradley and Jeremy Irwin.

The boys had been interviewed once before, on Oct. 4, the day their sister was reported missing from the family’s home in Kansas City, North. The boys were in the house the night she disappeared.

Since then, Kansas City police and FBI investigators have looked into hundreds of tips and leads.

Picerno said that the family plans to commemorate Lisa’s birthday today in private and asks that their privacy be honored.

“It’s going to be a tough day for them,” Picerno said.

Picerno said he and co-counsel, Joe Tacopina of New York, believe that investigators were too quick to point blame at Bradley and Irwin in the hours after their daughter was reported taken.

“There seemed to be an immediate rush to judgment exclusive of all other leads,” Picerno said.

Picerno also contested the public perception, fed by statements from investigators, that the parents have not been cooperative.

“Nothing can be farther from the truth,” Picerno asserted.

Kansas City police spokesman Capt. Steve Young reiterated Thursday night what he has said previously: that investigators are continuing to follow up all leads and tips they receive and that they have no suspects in the case.

He also said that investigators still would like to sit down with the parents and interview them separately.
