KANSAS CITY, Mo. -- The parents of 10-month-old Lisa Irwin arrived at a North Kansas City hotel on Friday evening, saying they appreciated the coverage of the case. An early morning dumpster fire on Tuesday led investigators to search a Johnson County landfill and by late afternoon Friday, the search had moved to the Irwin backyard.
In addition to the landfill search, the investigators with theFBI Evidence Response Team began searching the neighborhood around the Irwin home with metal detectors and by hand. There is no word on what investigators are looking for, specifically.
Police said someone reported a dumpster fire at an apartment complex at 4897 NE 37th Street at 2:27 a.m. on Tuesday, October 4. The dumpster is less than a half a mile away from the Irwin home.
Ten-month-old Lisa Irwin was reported missing by her parents around 4 a.m. Tuesday.
Investigators examined the trash from the fire two times. On Friday they examined it again. Also on Friday, police returned to the Johnson County Deffenbaugh Industries' landfill for the second time.

According to Tom Coffman of Deffenbaugh Industries, authorities told him that they were looking specifically for a body.
After four days of searching, the investigation into baby Lisa's disappearance has taken several twists and turns. On Thursday, police announced in a hastily-called press conference that 10-month-old Lisa's parents stopped cooperating with investigators, a claim the family denies.
On Friday afternoon, Kansas City Police Capt. Steve Young said they have not had contact with the parents since Thursday's announcement.
Retired FBI Agent Jeff Lanza said the parents' definition of cooperation is probably different than police's.
"Police's definition of cooperation is to answer any questions that we post to you even if it focuses on you," Lanza said. "The couple's definition is, 'well, we'll cooperate, but not if it's focused on us."
Late Thursday evening, FOX 4 learned Lisa's parents, Jeremy Irwin and Deborah Bradley, made a 'deal' with national news networks and would no longer be talking with local media.
On Friday's Today Show, Deborah said police told her she failed a polygraph test. Bradley adamantly claimed that's impossible because she doesn't know where her daughter is.
Lanza said failing a polygraph test doesn't mean someone is guilty.
"If you've registered some deception, that's an indicator that you're not telling the truth," Lanza said. "However, it doesn't mean you're guilty. It's just an indication that you're deceptive about a particular question or questions on the polygraph exam."
Neighbor Vickie Nichols told FOX 4 that failing a polygraph exam doesn't mean much to her.
"Personally, I've never had one, and I've never had any reason to do one, but I would think just being nervous would kind of, if I was being bombarded with questions and everything it would make me nervous. I might even fail one," said Nichols.
In the four-day search for Lisa, police have scoured the woods near the Irwin home, rappelled down embankments, looked in drainage ditches and on Friday, investigators turned their attention to Deffenbaugh's landfill.
According to the parents, baby Lisa was taken from her crib in her Northland home in the 3600 block of North Lister sometime between the hours of 10:30 p.m. Monday night and 4 a.m. Tuesday morning. The baby's father called police around 4 a.m. Tuesday when he came home from work and discovered her missing.
Lisa is described as white, with blond hair and blue eyes, about 30 inches tall and weighing 26-30 pounds. Her family says that she has two bottom teeth, a small bug bite under her left ear, a beauty mark on her right outer thigh and currently has a cold with a cough.
The family says that she was last seen wearing purple shorts and a purple shirt with white kittens on it.
