TIMELINE: From Gannon's disappearance to an arrest
Relevant portion
January 29: News 5 Investigates receives a credible tip from law enforcement sources, alerting us that Gannon was not a runaway child and foul play is suspected. Our sources disclosed that Gannon's stepmom was considered a prime suspect. As part of our fact-checking process, Chief Investigative Reporter Eric Ross reached out to Jacqueline Kirby, the media relations manager for the El Paso County Sheriff's Office along with Sergeant Deborah Mynatt, a spokesperson for the office.
"We will not be confirming any information that you have in your email," Kirby said. "This is an active ongoing investigation in the search for an 11-year-old boy. Any information prematurely released that has not been confirmed by the El Paso County Sheriff's Office would greatly hinder this investigation and would be very irresponsible journalism."[/QUO
That may be the time line but I don’t think news 5 published it at the time.
