LINCOLN, Neb. (AP) — A mistrial has been declared in the case of a 44-year-old Lincoln charged with sexually assaulting a 14-year-old boy he met through a networking app.

The jury deadlocked Thursday after several days of deliberation in the first-degree sexual assault trial of Esteban Bueno. Lancaster County District Judge Jodi Nelson declared a mistrial and set the case for retrial in April.

If retried and convicted, Bueno faces 20 years to life in prison.

Bueno was arrested last February after police say the boy told officers he and Bueno had chatted on the app and then met in person outside a Lincoln cafe. The boy said Bueno drove him to Bueno’s apartment, assaulted him there and then drove him back to the cafe.
