LOWELL, Mich. (WOOD) - Kent County sheriff's investigators said on Monday that they've received a number of tips, including one possible sighting of a missing Lowell-area man on Sunday night, since he was last heard from on Saturday evening.
A call to Silent Observer said a man fitting 62-year-old Robert Nylen's description was seen walking along the Grand River between his home in the 1100 block of Grand River Drive and the city of Lowell on Sunday evening.
However, investigators couldn't follow up on that tip because it was anonymous.
It has been a difficult weekend for the missing man's friends.
"A very stressful holiday weekend," Pauly Faba told 24 Hour News 8.
Faba and Pat Maloney, both friends of Nylen, fought swarms of mosquitoes and mud to search the banks of the Grand River near Lowell on Monday.
The last confirmed sighting of Nylen was Saturday at about 8 p.m. leaving the party store Faba owns on M-21, just across the river from Nylen's home.
"Right now, looking for his canoe. He often comes across, he only lives a few hundred yards that way," Faba told 24 Hour News 8 as he and Maloney searched along the shoreline.
Deputies with the Kent County Sheriff's Department Marine Patrol were on the water, checking the Grand River from Ionia to Plainfield Township.
Deputies were first made aware of Nylen's disappearance on Saturday afternoon.
A friend told deputies Nylen was having emotional problems because of some recent personal issues. He said Nylen jumped out of his vehicle near Buttrick Avenue and Grand River Drive.
Later, callers reported a man wandering in traffic and entering a swamp near Buttrick Avenue and Bolt Drive in Cascade Township.
Deputies went to both scenes to check for Nylen but didn't find him.
The all-out search began after a friend reported him missing Sunday morning.
Friends told 24 Hour News 8 they refuse to give up hope.
"Rob's resilient and he an experienced hiker, backpacker, fisherman," Faba said. "He's an outdoorsman."
If you have seen Nylen or have any tips in his disappearance, call the Kent County Sheriffs Department at 616.632.6100 or Silent Observer at 616.774.2345.
