Caylen Deller, 32, was found guilty of first-degree murder for killing Chad Mullen and burying him on her horse farm in San Mateo, Florida. After a trial that lasted several days, the jury deliberated for over an hour before convicting her. She received a life sentence along with convictions for tampering with evidence and failure to report a death. Deller claimed she acted in self-defense after Mullen choked her and threatened her with a hammer; however, prosecutors argued that contacting authorities would have been more appropriate than covering up the crime.

Story summary

Caylen Deller, 32, has been sentenced to life in prison for the first-degree murder of her boyfriend Chad Mullen at her horse farm in San Mateo, Florida. The verdict followed a guilty conviction on Thursday after less than an hour and fifteen minutes of jury deliberation. Additionally, Deller was found guilty of tampering with evidence and failing to report the death.

According to prosecutors, Deller killed Mullen when he allegedly choked her and threatened her with a hammer over unproven accusations that he had sexually abused her young daughter. She claimed self-defense but admitted to burying his body in a shallow grave and contacting him 28 times between September 2 and September 9, 2024, despite describing him as violent.

Deller was charged with first-degree murder following Mullen's death in September 2024, when her actions led to the discovery of his body more than a month later. The jury deliberated on evidence presented by prosecutors, including Deller’s inconsistent statements and behavior post-murder.
