Grant Wilson

Ghost Hunters' longtime co-lead investigator Grant Wilson is leaving the Syfy series this May, he announced on Wednesday's episode.

"While paranormal investigating has always been and will remain a passion for me, after enjoying nearly eight successful seasons on television, I have made the decision to leave the series in order to focus on other aspects of my personal life. I will deeply miss working with Jason and the rest of the dedicated investigators and crew that have become like family, and I wish them all the best as they continue to follow their passion and realize the vision of [The Atlantic Paranormal Society]," Wilson said in a statement. "I will also miss interacting with our wonderful fans worldwide. You are all at the heart of what we do on Ghost Hunters, and I'm grateful to have gotten to know many of you over the years."

Wilson's announcement on Wednesday's episode delivered 2.2 million viewers — the show's biggest audience in 15 months, according to Entertainment Weekly. Wilson will appear in six more episodes beginning in April, culminating with his final appearance on Wednesday, May 16 at 9/8c. Ghost Hunters International will take over the time slot for seven weeks beginning on Feb. 22.

"When Grant and I founded TAPS nearly 20 years ago, we never imagined that we would be able to make such an impact just by doing what we enjoy every day. I will miss working with Grant on a daily basis, and am indebted to the level of dedication and expertise he has brought to our field," co-lead investigator Jason Hawes said in a statement. "I can't imagine having a better partner through it all — both on the show and off. Grant and I, along with our spouses and children, are all like one big family. While I fully support his decision to move on from the series, this longtime friendship -- as well as our business partnership -- will continue off-camera for years to come."
