Before gunning down 12 people at a city building on Friday, a longtime public utilities engineer had emailed his resignation to superiors, giving two weeks’ notice just hours before the tragedy unfolded, officials said Sunday.
They did not provide any details about the gunman’s email or what else he did that morning.
“We’re determining where that letter is,” City Manager Dave Hansen said at a Sunday morning news conference. “He notified his chain of command that morning.”
Officials still did not provide any motive behind the killings, declining to discuss any evidence that law enforcement recovered from the shooter’s house.
