Lisa Irwin

In October 2013, a girl thought to be Lisa was discovered in a gypsy camp in Greece. Authorities determined the girl was not Lisa Irwin.

In May 2012, Deborah Bradley and Jeremy Irwin reported that their debit card had been fraudulently used on a website that provides false birth certificates. The Today Show and America Live both confirmed that the website existed. Their attorney also confirmed that he visited the website. Police have said they are continuing their investigation and they believe Irwin may still be alive.

The disappearance of Lisa Renée Irwin was reported after it was found that she was missing from her home in Kansas City, Missouri, in the early morning hours of October 4, 2011.

On October 19, 2011, a search was performed of the Irwin home, and court documents showed that a cadaver dog turned up a scent of a dead body that might have been Lisa, near the mother's bed. Items removed from the home at the time the warrant was executed include a multicolor comforter, purple shorts, a multicolor Disney character shirt, a Glo Worm toy, a "Cars"-themed blanket, rolls of tape and a tape dispenser.

In October 2011, Cyndy Short stopped representing the Irwin family, saying that she was unable to work with the family's other attorney, Joe Tacopina. Lisa's brothers had been scheduled for interviews and to collect DNA samples regarding the case, but their parents cancelled the night before, according to Tacopina, the family's attorney, and have allegedly denied investigators access to the boys. The boys had a second interview on November 10, 2011. A police request for a warrant claims that inconsistent stories from people involved may have hampered early stages of the investigation.
