AUSTIN (February 7, 2012)--Austin will install a flashing-lights traffic safety device at a crosswalk where two teens were struck and killed by a truck two days after Christmas.

A police investigation concluded the teens were looking at a hand-held device before they were struck, according to a Feb. 3 memo from city transportation director Robert Spillar to the Austin City Council.

Witnesses told police that Joshua Milton, 17, and Melodie Hewitt, 16, also failed to look to the left before they stepped into the street on Dec. 27.

Spillar says the teens were not within the marked crosswalk, at South First Street and Thelma Drive.

A crosswalk device will allow pedestrians to push a button and activate a flashing-light system that warns drivers to slow down and stop.
