To those who didn't know him, Jason Schmidt might have appeared rough around the edges.

"He was tattooed from head to toe," Susan Thomas, a close family friend, said Thursday. "But he was very loving and a good guy."

Schmidt, 31, of Jacobus, fell to his death Wednesday inside an empty water tower in Lower Providence Township, Montgomery County.

A coworker, identified Thursday as Miguel Martinez, 38, of Penns Grove, N.J., spent three hours suspended in midair by his safety harness inside the tower until he was saved in a dramatic rescue.

A firefighter from Norristown was eventually lowered into the tank on a rope and rappelled 60 feet to ground level with Martinez.

Martinez was taken to Paoli Hospital after his 31/2-hour ordeal but was not admitted, officials said.

Montgomery County Coroner Walter I. Hofman said Thursday that Schmidt died after suffering "multiple injuries" in the fall and ruled his death an accident. A third worker was uninjured.

They were employed by Corrosion Control Corp., a Salem

County, N.J., firm where Schmidt had worked for 14 years, following in his father's footsteps.

Family reeling: On Thursday, Thomas said Schmidt's family was reeling. Schmidt and his wife, Amy, had a 2-year-old son, plus responsibility for five other children from previous relationships.

Thomas said she had known the Schmidts for several years. Her son, she said, once was engaged to marry Amy, but he was killed in a car accident 11 years ago. The two women have remained close.

She said she loved Jason Schmidt "like a son."

"I lost a son and worried about who Amy would marry, if they were going to be good to my grandkids. I never had to worry about that with Jason," she said.

Schmidt enjoyed simple pleasures, Thomas said -- playing with his children, riding his motorcycle, "being a goofball." He grew up in New Jersey but later moved to Pennsylvania, and he and his wife had met at a Ruby Tuesday's where she was working five years ago.

"It's rough," Thomas said. "We're all going to try to help each other. It'll definitely be a void in our life without Jason in it."

Investigation: Answers on what exactly went wrong were still wanting the day after the accident. The Occupational Safety and Health Administration was investigating, Hofman said. Corrosion Control representatives did not return calls for comment.

The company has been inspected by OSHA three times before. Two inspections, which took place in Harrisburg, were routine but one found "scaffold fall protection violations," according to OSHA.

In 2008, OSHA investigated a workplace fatality involving Corrosion Control in Philadelphia. The company ended up paying $12,810 in fines.

Lower Providence officials said they believed that in Wednesday's incident, the workers' equipment malfunctioned, but they would not elaborate. After receiving an emergency call from the uninjured worker in the water tower, rescue crews spent hours trying to reach Martinez.

About 50 people participated in the rescue, both on top of the tower itself and on the ground.
