A Peoples Gas worker killed when an underground pipe he was pressure-testing burst apart on Wednesday was a great husband, father and coach, those who knew him say.
"They were pumping air through the system when something went wrong," a fire department spokesman said. "It blew the pipe apart, and it hit them."
No gas was involved, the utility said.
Gryga was an assistant coach for the Lincoln-Way Blue Wave girls softball team. His daughter, Megan, plays for the organization's 16-and-under team, said Joe Chimienti, who coached with Gryga.
"I just saw him two days ago at team pictures. I talked to the guy two to three times a week," Chimienti said, adding that Megan and her twin brother, Mike, are sophomores at Lincoln-Way East High School.
Deanna Blyth, manager of the team, said Gryga was an extremely dedicated coach.
"Mike was a wonderful assistant. I think the reason is because he's such a wonderful husband and father," Blyth said. "We were fortunate to have him work with the girls."
A second employee remained in critical condition at John H. Stroger Jr. Hospital of Cook County, a Peoples Gas spokeswoman said.
Kevin Spillers, a trader at the Board of Trade, was walking nearby and jumped into the hole after hearing a loud boom. He helped get the men out of the underground cavern when emergency personnel arrived.
Spillers told the Chicago Tribune that he doesn't consider himself a hero, but Gryga's siblings disagree. They both wrote e-mails to the newspaper commending Spillers.
