DETROIT (AP) — Family members of Matt Mika say the Michigan native suffered multiple gunshot wounds and remains in the intensive care unit in critical condition after surgery.

Mika was wounded Wednesday when a gunman opened fire at a baseball practice, injuring a congressman and others.

His family said in a statement late Wednesday that they expect Mika to remain hospitalized for at least several days. The family said, “we continue to be in disbelief that he would be part of this heinous attack.”

Mika is a former aide to Michigan Republican congressman Tim Walberg. He is director of government relations for Tyson Foods Washington, D.C., office and has worked for the company for more than six years.

Mika’s family described him as “a very thoughtful, fun-loving person who is competitive and loyal; all things which contributed to his continued commitment to the Congressional Baseball Game.”
