First he was silent, then he disappeared. Here's a timeline of the search for Brian Laundrie

It's now been more than three weeks since Brian Laundrie went missing after returning without his fiancee, Gabby Petito, from a cross-country trip.

The case has had constant updates that have left authorities and the public confused as to the timeline of and reasons behind Laundrie's disappearance. His parents have made little to no comment surrounding the case, as well.

Laundrie family attorney Steven Bertolino has previously said Laundrie's parents are "remaining in the background" and would not comment on the advice of counsel. Bertolino has said the Laundries don't know where their son is and haven't heard from him since he left their Florida home around mid-September.

Laundrie has not been charged in the death of Petito, whose body was found in Wyoming. He was indicted on charges of using two financial accounts that did not belong to him in the days following Petito's death.
