Benjamin Ashford|Man fishing with his son drowns after rescuing 2 other children swimming at Pennsylvania state park

A man drowned after rescuing two children who got into trouble while swimming at an eastern Pennsylvania state park, authorities said. The Bucks County coroner's office said Marvin Alexan Fernandez Chicas, 37, "disappeared in the water" after rescuing the children who were swimming at Nockamixon State Park on Thursday evening.

An online fundraiser launched by the family said Chicas, who worked at a local horse farm, was fishing with this 3-year-old son at the time of the incident.

"He was a man who liked fishing and that day he is doing what he liked together with some friends and son, unfortunately he died drowned in the lake giving his life for two children who were also about to drown along with him," his family said in the GoFundMe page.

The GoFundMe, which called Chicas a hero for his actions, had raised over $36,000 by Monday morning.

The coroner's office said Friday that the cause of his death had been confirmed as drowning following an autopsy and the manner of death appeared to be accidental. Coroner Meredith Buck said in a statement that the office is extending "its deepest condolences" to his family.

Wesley Robinson, spokesperson for the Department of Conservation and Natural Resources, said the two children were seen struggling in the Tohickon Creek in the cliffs area at about 5 p.m. Thursday. Chicas went in and got the children to shore, then began to struggle, Robinson said. His body was found by divers in the lake more than two hours later.

Swimming is prohibited in the creek and in the 1,450-acre Lake Nockamixon, the largest in the county, Robinson said.

Fire Chief Harry Grim of Haycock Township, who said about 10 divers were involved in the search, told WFMZ-TV that many parts of the lake are deceptive and dangerous.

"Unfortunately, people don't follow the rules, and the sad reality is it's not a smooth, gradual slope under the water, and they step off into a deep area, they take a gulp of water, and they die, unfortunately. It shouldn't happen, but it does," Grim said.

Grim told WFMZ-TV that Chicas was located about 25 feet from shore. The two children were not injured.
