Company records from Accent Signage released Monday by the Minneapolis Police Department show that Andrew Engeldinger was reprimanded for chronic tardiness just a week before he went on a shooting rampage that left six people dead.
According to the more than 100-page personnel file, Engeldinger was late to work 35 days in a row in August and September.
On Sept. 20, Accent Signage quality control manager Rami Cooks sent Engeldinger a letter stating that his constant tardiness was a problem that needed to be, quote, "rectified immediately."
The file shows that Engeldinger received a similar letter in 2011 about another string of late arrivals. Manager John Souter also entered several letters going back to 2006 in Engeldinger's file that described incidents where co-workers said he was verbally abusive towards them.
Police say Cooks and Souter were the first two people Engeldinger shot. Cooks later died at the hospital. Souter survived.
Engeldinger killed himself before police arrived.Police release details from Accent Signage shooter's personnel file
