Lisa Irwin and Unrelated Stabbing Incident

Missing baby Lisa Irwin's parents, Deborah Bradley and Jeremy Irwin, have filmed a segment for the Dr. Phil Show. The Kansas City Star reports that the show is set to air on Feb. 3, exactly four months since the day Bradley and Irwin say they last saw their daughter.

They sat down with Dr. Phil because of his commitment to keep the awareness level high, Joe Tacopina, the couple's New York attorney, told KCTV 5. He also provided Deb and Jeremy with some advice on how to cope with the situation.

Baby Lisa has been missing since late Oct. 3 or early Oct. 4, when the then-10-month-old girl mysteriously disappeared from her bedroom. Lisa's father, electrician Jeremy Irwin, returned home to find his daughter missing and his wife, Bradley, asleep with the couple's two sons. He called 911 to report the disappearance immediately.

The night of baby Lisa's disappearance a window and screen were tampered with, lights were left on, the family's front door was unlocked and three cell phones were missing. Deborah Bradley said she last saw her daughter at 10:30 p.m. before falling asleep in bed. Bradley later admitted she had been drinking wine and may have been drunk that night.

Baby Lisa's disappearance has prompted a national four-month search.

Investigators closed an outpost dedicated exclusively to solving the case in late November, however authorities have continued following the case in their main offices in Kansas City. Although Kansas City Police Capt. Steve Young insists the case is not closed, investigators have been encouraged to take on new cases due to a pile-up of child neglect and abuse cases. Young claims there are not enough resources to focus wholly on baby Lisa Irwin, especially as police have received fewer tips in the past few weeks compared with the previous several weeks.

The search for missing baby Lisa Irwin continued Jan. 15 as police teams searched near Interstate 435 and Parvin Road near Kansas City. While police refused to reveal what information led them to search this area, KCTV-5 reported police have not conducted a major search of this particular region since mid-November. It is unclear why police decided to revisit the area in search for baby Lisa, however they have not reported finding any conclusive evidence.

Police say Bradley and Irwin have been uncooperative and have refused to be interviewed separately by police. Lisa's parents have asked that supporters cease their candlelight vigils and have expressed hope that their life can return to normal. Onlookers wonder how the parents can even hope to live a normal life when their 1-year-old daughter has been missing for over three months.

Authorities continue to maintain they have no major suspects or leads in the case. Investigators closed an outpost dedicated exclusively to solving baby Lisa's case in late November and authorities are now addressing the case in their main offices in Kansas City.
