LINCOLN, Neb. (AP) — City workers have increased patrols of Lincoln’s parking garages following the suicides of two people who jumped to their deaths this week.

City parking manager Wayne Mixdorf said he didn’t think it was necessary to modify the buildings, such as by erecting fencing.

But Mixdorf says maintenance workers and managers have begun patrolling the garages more frequently.

The move follows the death Thursday of an 18-year-old high school student and the Monday death of a 28-year-old.

They were the fourth people to jump to their deaths in Lincoln since 2008. During that period, Lincoln police say there were 197 suicides in the city.
