A Seminole woman is jailed after what authorities describe as a terrifying, premeditated attempt to kill her husband — and, by her own words, their son. Deputies with the Pinellas County Sheriff’s Office arrested 58-year-old Karen Ruth Dedert on Tuesday and charged her with first-degree attempted murder, a domestic-related offense, after neighbors and her husband called 911 following a series of early-morning attacks at the couple’s home on Tara Cay Court.

According to the arrest affidavit, the incident began just after 5 a.m. when the husband awoke to find his wife asking about their son’s whereabouts. Dedert allegedly told him, “I need to sacrifice and kill you both,” then lunged at him with a large knife. He managed to fend her off, disarm her and lock himself in a bedroom, the affidavit says, but the violence did not end there.

Hours later, the man left the room to shower and — prosecutors say — Dedert ambushed him again, emerging from behind a refrigerator and aiming a knife at his abdomen. The husband says he raised his arm to protect himself and suffered a laceration to his left forearm before he was able to escape the home and call police. Deputies arrived around 8:15 a.m. and detained Dedert without incident.

When first Mirandized, Dedert initially declined to speak with investigators. She later told deputies, “These aren’t the clothes I was wearing when I stabbed him.” Court records and local reporting later showed a $100,000 bond was set, with conditions that included GPS monitoring and no contact with the victim.

There’s a lot going on in this incident. She tried to stab her husband multiple times, and she allegedly said, “I need to sacrifice and kill you both.” This is more than a domestic incident, it’s a sign of something much more upsetting.

Prosecutors will now decide whether to pursue the most serious charge leveled against Dedert — first-degree attempted murder — which requires proving a specific intent to kill. Defense lawyers routinely point to issues of intent and mental state in such prosecutions; the public record so far contains little information about Dedert’s mental-health history or any prior domestic calls at the residence.

The sheriff’s office says the investigation remains active; court dates and further filings will determine whether prosecutors can prove the allegations beyond a reasonable doubt and whether the victim and his family will have their day in court.
