GRANDVILLE, Mich. (WZZM) -- The search continued Monday along the Grand River for a Grandville woman missing since the weekend.

51-year old Mary Tornga disappeared around 1:00am Sunday, after arguing with her husband.

They were driving home from a birthday party in Grand Rapids, when Tornga got out of the car near Market Street and I-196. She hasn't been seen since.

Grandville Police Chief Dan Steer says the family reported her missing later that day. Police decided to take action soon after she was reported missing. "Due to the fact that she was down here, middle of the night, with the water, the river being a concern too."

Monday afternoon, the Michigan State Police used its helicopter to search up and down the Grand River. There were no plans to search the river. "No, we're not going to put any divers in, heavy current, lots of snags, very dangerous to put boat in. We wouldn't even know where to begin."

A shoe, belonging to Tornga, was found near the area where she disappeared on Sunday evening. Police also tried to call and track her cell phone, but it appears to be turned off.

Grandville Police say the Tornga's husband is talking with police and is not considered a suspect.
