Hundreds of volunteers gathered at Mountwood Park Saturday to join a search party to find 28-year-old Gretchen Fleming. The Wood County woman has been missing for more than two months. The teams used a grid search technique throughout the park, including the area around Harmony Ridge Recovery Center in response to multiple tips police have received regarding the area. Gretchen Fleming was last seen at the My Way Lounge in Parkersburg on Dec. 4. Police have said they have a person of interest, but declined to name that person to protect the investigation. A reward of up to $65,000 has been posted for information regarding Fleming’s disappearance.
