IOWA CITY -- Just about everyone who knew Steven Sueppel describes him as a man who cared deeply about his wife and kids. Understanding why he killed his family has been difficult for many people.

The children were always by Steven and Sheryl's side. Sister Agnes Giblin knew all four Sueppel children well, and says they were always polite, kind and caring.

“I would give them books. An occasion never went by that they got something from me that I didn't get a thank you note from each one of them...whether it was a scribble or whatever, but their names were signed to it," Giblin said.

10-year-old Ethan was an aspiring cello player who impressed everyone with his musical abilities. He also loved to play soccer and other sports. "He was his grandfather's golf-partner. He'd always go golfing with his grandfather. He always was very smiley and outgoing," Giblin said.

8-year-old Seth was much different from his brother. "A little more shy, Seth loved animals. He had two pet rabbits that were very special to him," she said. He also loved gardening flowers and vegetables.

Mira was supposed to celebrate her sixth birthday this week. "They called her the boss. She loved to dress up," Giblin said.

Little Eleanor never spent much time apart from her Barbie dolls and her dress up clothes. “Eleanor was very docile, very loving..she was always very patient," Giblin said. She was only three-years-old and family called her "the princess."

All four children had big hopes and dreams that Sister Agnes believes will come true in heaven.

Sister Agnes was also Steven Sueppel's third grade teacher. She was there when the couple got married and when they adopted all four children. This weekend, she'll be at their funeral.
