Investigators launch new search for Lisa Irwin in park about 2 miles from her home

KANSAS CITY, Mo. - The search for Lisa Irwin took investigators on Thursday to a park about two miles from the 11-month-old girl’s home.

Authorities with the FBI and Kansas City Police Department searched Chaumiere Woods Park, in the 3700 block of NE 43rd Terrace. That's near Interstate 35 and Chouteau Trafficway, about two miles north of Lisa’s home in the 3600 block of Lister Avenue in Kansas City.

NBC Action News reporter Lindsay Shively reports one boat was in a lake there, and two more ground crews were searching the area. All three had dogs.  At various points in the search the dogs could be heard barking, but nothing was pulled from the lake. Police say the search was not based off of any specific tip. 

After searching the area for several hours, investigators left without finding any evidence in connection with the Lisa Irwin investigation.

Lisa was reported missing on Oct. 4. Her parents said Lisa’s father, Jeremy Irwin, came home around 4 a.m. and Lisa was not in her crib.

Sgt. Stacey Graves with the Kansas City Police Department said nearly 800 leads have been followed up on by police.
