"In fact, this is the first time we've handled something like this," he said.
Crime Stoppers takes anonymous tips from the public and then turns them over to investigators. With more than 250 tips that police are investigating, at least 148 came through Crime Stoppers.
"Most of the information we're receiving right now doesn't have a lot of detail," Boehm said. "That's really what the investigators are looking for. They're looking for specific information."
Information that will help them solve the nearly week-long mystery.
"Anybody that saw anything that happened that night -- Monday night into Tuesday morning, anything that was suspicious in the area, specific reports of vehicles, license plates, descriptions of people that look out of place; anything like that would be helpful," said Boehm.
"Or if the individual is out there that may have Lisa, if they want to report that information to us and return the child - obviously we're going to take that. It's all anonymous - no questions asked. We want Lisa back."
Kansas City's TIPS Hotline started back in October of 1982. Just last week law enforcement made its 10,000 arrest in relation to information received through the hotline. Now officers hope that a tip to crack the case of missing Lisa Irwin will bring their number to 10,001.
The TIPS Hotline is available online, over the phone and via text 24 hours a day. Tipsters remain anonymous and can collect a cash reward if an arrest is made in the case.
