Maryland State Police have still not released the name of the driver who killed two highway workers in a Route 40 work zone near Perryville on Jan. 9.

The driver was on Route 40 near Belvidere Road at about 9 a.m. that day when he struck and killed Luis E. Tadeo, 42, of the 1500 block of Palai Turn in Bowie, and Victor D. Jackson, 41, of the 5500 block of Hunt Place N.E. in Washington, D.C.

They worked for a State Highway Administration contractor, the SHA said.

The driver was operating a 2006 Ford Focus, according to a state police press release at the time.

Both victims were pronounced dead at the scene by emergency medical personnel from Cecil County, State Police said.

The driver "was taken into custody for questioning. He was released without charges and is not being identified at this time due to pending charges," a State Police spokesman said. "He was not injured."

It is not known why the car entered the work zone and it is not known how fast the car was traveling, according State Police, who said the accident remains under investigation.

State Police spokesman Sgt. Marc Black said the Focus was traveling in the westbound lane when it veered into the work zone. The crash scene is about two miles east of Perryville.

The work zone was marked off with orange traffic cones and other safety equipment, he said.

State Highway Administration officials responded to the scene and closed Pulaski Highway to westbound traffic in the Belvidere Road area for several hours.

The Cecil County State's Attorney's Office was also notified, State Police said.

According to the State Highway Administration, the area along Route 40 where the accident occurred is part of a project to improve storm water management and water quality.

Workers were in the process of placing barrels as part of the traffic management for Wednesday's work when Jackson and Tadeo were killed.

Anyone with information about the accident is asked to contact Maryland State Police at the North East Barrack at 410-996-7800.
