"He was a solid, dependable person," said Zolinas, who searched the creek for Kvaraciejus' body for eight hours yesterday, adding that he and others would return today. "We're not going to stop trying until we find him or until someone else finds him. If I had perished, he would do the same thing."
Kvaraciejus was a sophomore at Penn State. A woman who identified herself as his aunt said he was set to leave for the Marines today. She said her nephew "enjoyed everything that a boy his age would enjoy."
She added that it's unfortunate that "something like this has to happen before young people realize" the dangers of swimming in the city's creeks.
Police officials said that every summer, people swim or play in the city's creeks, streams and rivers, which are unpredictable and extremely dangerous.
"It's not a good idea," said Joanne Dahme, general manager of public affairs for the Philadelphia Water Department. "We want people to visit the streams because it's important to appreciate them. But we just ask that people not try to swim in them. They're not safe."
Hours before Kvaraciejus disappeared, Andrew Watts was rescued Tuesday morning from the Pennypack Creek a few miles away, when the water rose from a few inches to a few feet in a matter of seconds.
"People underestimate the power of water," said Lt. Andrew Napoli of the Philadelphia Police Marine Unit. "At any time, there can be a flash flood and the conditions can get a hundred times worse. There's no way to be able to handle that."
Unlike the city's pools, experts say creeks and rivers can be especially dangerous because you can't see the depth of the water, which is filled with toxins and bacteria following heavy rains. There are also no lifeguards and there are hidden hazards including rocks, logs and debris, like metal scraps and shopping carts.
"It is completely different from a swimming pool," said Police Chief Inspector Scott Small. "A swimming pool is controlled, it's not moving and there is no flow."
Small said it is illegal to swim in some creeks, including the Tacony, Pennypack and Frankford creeks. But state law, warning signs restricting swimming, and police patrols are still not enough to keep people out of the water.
Generally, Pennypack Creek can range from a few inches in some areas to a few feet. But the water where Kvaraciejus disappeared Tuesday night was between 10 and 15 feet high, Small said, because of the storm.
"I think he liked to try and live life on the edge," said Kvaraciejus' friend, Kevin Battersby.
The Police Marine Unit will resume its search for his body this morning.
