It has been three months since Lisa Irwin, an infant from Kansas City, was reported missing. Now, for perhaps the first time, it seems the police have a substantial lead to help with their investigation; at least according to John Picerno, a Kansas City attorney acting for Lisa's parents, Jeremy Irwin and Deborah Bradley.

Picerno, who spoke on Tuesday, said investigators actually had several leads, one of which was particularly promising and although he would not reveal details, added that both the local police and the Federal Bureau of Investigation (FBI) were aware of the leads.

The Kansas City Police Department, however, has not commented on these statements.

Lisa was reported missing on the morning of Oct. 4, when her father, who was undertaking electrical work at a local Starbucks, came home at 4 a.m. and found her missing. He also reported that when he reached home the front door was unlocked and three mobile phones were missing.

Both Irwin and Bradley have been under suspicion since Lisa's disappearance, particularly over having refused to meet with the police separately, based on their attorney's advice. In addition, Bradley admitted to have been drunk enough to have passed out, on the night prior to the reported disappearance.

There is a reward of $100,000, announced by private and unidentified donors, for anyone who provides information leading to Lisa's recovery.
