OAK CREEK, WI (WTAQ) - A former soldier now says he regrets covering up for Wade Michael Page, when the Oak Creek gunman tried to commit suicide in 1997 over the breakup of a girlfriend.

Christopher Robillard served with Page in the Army’s psychological operations corps. He said Page was so distraught after his breakup, that he and his friends broke into Page’s apartment to make sure he didn’t kill himself. And sure enough, they found him passed out from alcohol.

Robillard tells the Milwaukee Journal Sentinel that he and friends kept it quiet at the time – and they should have reported it to authorities.

Jennifer Dunn, a psychiatric nurse who lived in Page’s duplex in Cudahy, said it could have been one of dozens of signals that were missed. She told the Journal Sentinel that if anyone had evaluated Page, a, “gazillion red flags would have gone off.”

Dunn said it was more than obvious that Page had a “huge mental illness.” But she never called police because he never did anything that was dangerous enough to send him to an institution.

Earlier reports said Page had a drinking problem that resulted in an Army demotion, and the loss of a job as a commercial truck driver.

Friday, a visitation and memorial service will be held for the six Sikh Temple members that Page shot and killed last Sunday in Oak Creek.
