YAKIMA, WA. -- A Yakima police officer is on administrative leave as the department investigates his conduct during the Yakima Canyon double murder case in 2012.
The internal investigation is more than 200 pages long. In it, investigators claim that Officer Geoff Gronewald had an inappropriate relationship with a victim's ex-girlfriend and shared confidential information with her.
In December 2012, two people were found murdered in a car in the Yakima Canyon. One of them was Michael Eby, whose body was stuffed into the trunk of the car. Detective Geoff Gronewald knew Eby before the murder and was even texting him the morning of the incident. Eby was an informant for the detective.
According to a massive internal investigation by the Yakima Police Department, Detective Gronewald started a intimate relationship with Eby's ex-girlfriend, Shannon Rosales, shortly after the murder.
Investigators say during the relationship, Gronewald sent Rosales hundreds of unauthorized text messages, including pictures. Some of the texts allegedly included sensitive information pertaining to the murder case.
In January 2013, Gronewald was there when officers searched a home looking for evidence. On that day, the detective sent 175 texts to Rosales. In interviews, Rosales admitted to police that she believed the texts were inappropriate.
During this entire investigation, Detective Gronewald did not write a single police report detailing his involvement. Something Gronewald says in interviews that he simply forgot to do.
Gronewald also said he doesn't believe he released any information that changed the outcome of the case in which four people have been arrested and await trial. Investigators have charged Gronewald with acting inappropriately, releasing confidential information and failure to report investigative actions.
Detective Geoff Gronewald is scheduled to meet with investigators and the chief of police for a pre-disciplinary hearing next Tuesday.
