Lisa Irwin and Unrelated Stabbing Incident

Deborah Bradley and Jeremey Irwin allowed missing baby Lisa's half-brothers to be interviewed Thursday afternoon for the first time since an initial conversation occurred with police the day after Lisa went missing from her Kansas City home over a month ago. The two half-brothers, 5 and 8, were home the night baby Lisa went missing and reportedly claim they heard noises, according to Bradley.

The interviews Thursday were conducted by child specialists, Darin Snapp, Kansas City Police Department spokesman told Reuters. Snap did not release any further information regarding the interviews, but police will have access to the boys' responses. They hope the interviews will lead to further information that might help in the investigation.

Baby Lisa's parents, Jeremy Irwin and Deborah Bradley, had initially agreed to allow interviews for their boys approximately two weeks ago, but they were delayed after problems occurred between the family's lawyers.

Over one month has passed since parents, Deborah Bradley and Jeremy Irwin, reported their daughter, baby Lisa Irwin, missing from her crib in the middle of the night on Oct. 4. The missing 11-month-old will celebrate her first birthday Friday, but she is still nowhere to be found.

The case began when Lisa's father, Irwin, returned home on Oct. 4 after working overtime to find the door open, the lights in his house on, windows tampered with and his daughter missing. Lisa's mother, Bradley, had allegedly put her daughter to sleep around 6:30 p.m. and proceeded to drink five to 10 glasses of wine before passing out around 10:30 p.m. Since Oct. 4, authorities have scoured the surrounding area following all major tips and leads, but they have found no signs of baby Lisa.

The investigation has hit a standstill, though police maintain they have not closed the case. However, police have stopped searching the areas surrounding baby Lisa's Kansas City home, stating they have run out of places to look, The Washington Post reported. Media attention has also slowly waned with fewer reporters waiting outside the Bradley-Irwin home and requesting interviews.

We are not doing any physical field searching just to do it, Kansas City Police Capt. Steve Young said Thursday reported the Washington Post. If we have another idea, thought or piece of information on where to do that, we will do it before you can blink. But we aren't going to do it just to do it. We're not going to close our eyes and start throwing darts.

Baby Lisa's parents, Deborah Bradley and Jeremy Irwin, continue to maintain their silence. The couple has not spoken publicly since they allowed their family to be followed by a national television crew on Halloween. Lisa's parents also have limited interviews will police and have not spoken to police separately since Oct. 8.

Joe Tacopina, the New York Attorney representing Bradley and Irwin, claimed he would give a statement Friday addressing the half-brothers' interview. He also said that Lisa's parents will not be giving any more media interviews as attention should be focused on the search for baby Lisa.

New questions have surfaced in the investigation regarding three cellphones stolen from the Bradley-Irwin home the night of baby Lisa's disappearance. Phone records indicate that Lisa's mother's cellphone was used to make a 50 second phone call to Megan Wright, the ex-girlfriend of neighborhood handyman, John Jersey Tanko. Tanko has a criminal record and has been extensively interviewed by police. He is known to do work around the Kansas City neighborhood and was reportedly seen that night by a neighbor near the Bradley-Irwin home.

Wright, however, has denied the reports, claiming she never received a phone call from Bradley's phone. She says the cellphone is shared by seven other people and she did not have the phone in her custody when the alleged call was made.

Despite the new questions, there are still no major suspects or leads in the case although over 1,200 tips have been reported and over 900 have been pursued. Snapp maintains that every tip that warrants a search has been and will be followed.

We still investigate every tip we receive, nothing has changed with that, Snapp told Reuters.
