KANSAS CITY, Mo. - Lisa Irwin disappeared six months ago from her parent's Kansas City home.
Lisa's parents, Deborah Bradley and Jeremy Irwin, have maintained their innocence during the entire investigation. Jeremy Irwin said he came home from an overnight shift to find Lisa missing from her room. Deborah Bradley said she was sleeping when the discovery was made.
Police issued an AMBER Alert for Lisa. Crews searched several miles around the home. Tips are still coming in for Lisa, but police said the leads have slowed dramatically. Police have worked 1,561 since October 2011, but only 11 leads were received in March.
"There are still four detectives that are actively working the case on a daily basis and up to an additional six if/when the volume of leads requires," said Cpt. Steve Young.
Young said detectives will consider the case "cold" once all leads are investigated and cleared.
The family isn't speaking publicly, but their attorney said they are still hopeful.
"The family is still hopeful that Lisa is alive and will be found soon and return safely," said John Picerno.
