Cedar Rapids, Iowa — A Tama County woman accused of murdering her husband took the stand Thursday in her own defense during a high-profile trial. Karina Cooper faces first-degree murder charges in connection with the death of her husband, Ryan Cooper, who was found shot to death in their home in Traer in June 2021.
Ryan Cooper died from two gunshot wounds to the face, leading to an investigation that resulted in Karina’s arrest in February 2024. Throughout the six-day trial, she has been the sole witness for the defense, offering a narrative complicated by her alleged fear of another individual.
On the witness stand, Karina Cooper stated she suspects Huston Danker to be the person responsible for her husband’s murder. She explained she never reported her suspicions to law enforcement due to fear of Danker. The two were reportedly involved in an online relationship that became physical just four months before Ryan’s murder.
Karina described that their affair initially began as an online fantasy. However, when it transitioned to an in-person relationship, she became alarmed and worried about the repercussions for her marriage. Despite these concerns, she acknowledged that she continued to communicate with Danker, who, she claimed, made multiple threatening comments about Ryan.
One significant remark attributed to Danker involved a chilling suggestion about Ryan’s potential death. Cooper recounted that Danker had said, “If you get home and find your husband dead, make sure you pick up those shotgun shells for me,” explaining that he referenced criminal investigation shows to justify his comment. Karina saw this conversation as a signal of Danker’s sinister intentions, but she claimed fear kept her from reporting him.
In a striking revelation, the prosecution presented Snapchat messages exchanged between Karina and Danker an hour before Ryan’s murder. One of Danker’s messages urged her to “remember those casings,” to which she responded, “Absolutely. 100 percent.” The prosecution emphasized the implications of her response in the context of the murder investigation.
When questioned about her choice of words, Karina insisted she had sent additional messages urging Danker to “go to sleep,” a claim contested by a digital forensics investigator. Tiffany Lord testified that the messages suggested a more direct instruction from Cooper to “go,” calling her portrayal of the conversation into question.
Despite her testimony, Karina admitted she never disclosed her suspicions about Danker to investigators or others. She attributed this silence to fear of his threats, yet she hadn’t communicated the threats to anyone.
The trial is expected to continue with closing arguments anticipated by Friday, marking a significant chapter in a case that has captivated the local community.
