ST. PAUL, Minn. (AP) - The parents of a man who killed six people before committing suicide in Minnesota's worst workplace shooting say they tried for years to persuade him to seek psychiatric help, but he refused.

Andrew Engeldinger killed himself at the end of a rampage through Accent Signage Systems that began when he was fired Sept. 27 for lateness and poor performance.  Two of his other victims survived.

Chuck and Carolyn Engeldinger say their son had shown signs of mental illness for many years. They believe he had schizophrenia, though he never submitted to being diagnosed.

They say they couldn't get him committed because he was over 18 and had not been a danger to himself or others before the shootings.
