A California woman has been convicted of murdering stepfather after she found nude photos of herself on his computer.

The interior designer was convicted of first-degree murder Wednesday after prosecutors said she killed her butterfly conservationist stepfather when she found nude photos of herself on his computer.

As the San Diego County jury read its verdict against Jade Sasha Janks, 39, of Solana Beach, her eyes widened and she appeared to be in stunned disbelief as she turned toward her defense lawyer.

Janks, who had been free on bail, was immediately taken into custody. She faces 25 years to life in prison for the slaying of Thomas Merriman, 64, a co-founder of Butterfly Farms in Encinitas. She is next due in court on April 3.

Deputy District Attorney Jorge Del Portillo thanked jurors for their verdict.

“They’ve been excellent and patient and kind and attentive throughout this whole trial, and we’re just happy we achieved some justice for Tom and his family,” he told reporters outside the courtroom in Vista.

Merriman was killed on Dec. 31, 2020, not long after Janks found the compromising photos on his computer.

Janks drugged Merriman, suffocated him with a plastic bag and choked him to death, prosecutors said. A text message Janks sent to an acquaintance the day Merriman died, which was shown to jurors, read: “I just dosed the hell out of him.”

Janks’ defense insisted Merriman died from poor health and chronic drug abuse. His official cause of death was listed as an overdose of prescription sleep medication.

Defense lawyer Marc Carlos said he is evaluating all avenues for appeal. He conceded that text messages Janks sent were pivotal in the jury’s decision.

Jurors rejected lesser charges, such as manslaughter and involuntary manslaughter, which could have allowed a judge to consider mitigating circumstances at sentencing.

“The reason why Jade went to trial was she believed she was not guilty of this thing, and that’s been her position through the whole case,” Carlos told NBC News on Thursday.

Carlos said he understood his client’s stunned reaction.

“It’s just a surreal situation to be in,” he said. “When the jury walks in, hands the note to the judge, the judge reads the note and then the note goes over to the clerk and the clerk begins to read it, it’s like an eternity. So it has a lot of psychological stress.”
