As Andy Sporleder waited Monday for the arrival of his son’s body, he described the atmosphere as calm.

"You know, we’re doing pretty good, really," he said from his home in Sylvania, Ohio, where friends and family members had gathered. "We are aware of the fact that he isn’t coming back."

Kyle Sporleder, 20, of Sylvania, was one of four people killed Sunday in a crash on the Indiana Toll Road near New Carlisle, Indiana State Police revealed Monday.

The other three victims have been identified as Aaron F. Esposito, 23, of Novi, Mich.; Lauren Diefenthaler, 19, of Ypsilanti, Mich.; and Rodney M. Echelbarger, age unknown, of Holland, Ohio.

According to police, about 8:05 p.m., the four were eastbound about 10 miles west of South Bend when their car slid across the median and into the path of a westbound semi-truck.

The road was reportedly covered with snow and ice.

Three of the victims were pronounced dead at the scene, police said, and the fourth died later at an area hospital. The driver of the truck, Duane Rigdon, of Carlsbad, Okla., was not injured.

According to Andy Sporleder, Kyle and the other three victims worked for Amway Global. He said they had attended a conference in West Lafayette, Ind., on Saturday and were returning Sunday when the accident occurred.

"They were all business partners," he said. "They were in this business together."

Kyle Sporleder and Echelbarger were also both lance corporals in the Marine Corps Reserves, according to Capt. Nathan J. Braden, with Marine Forces Reserve Public Affairs. Both were inactive.

Andy Sporleder said his son knew Diefenthaler and Esposito as colleagues, and met Echelbarger in the Marines.

He said his son joined the Marines out of high school.

"It was just something he wanted to do," Andy Sporleder said. "He wanted to make a difference."

Sporleder said his son left for West Lafayette sometime Friday or early Saturday. He said he hadn’t spoken to him at all over the weekend.

"He was a go-getter," he said. "He had a plan with this business of his. He knew where he was going and what he wanted to do. He had a fire in him that you just couldn’t put out."

Of the accident, he said, "He was just in the wrong place at the wrong time, I guess."
