The lockdown was in effect for about two hours and was finally lifted shortly after 4pm, Klein ISD says. The schools affected were Klein High School, Klein Annex, Kleb Intermediate and Mittelstadt Elementary.
The Harris County Precinct 4 Constable's Office says the search for the murder suspect, who was believed to have a gun, began near York Minster and Wimbledon Estates after investigators say a tip led them to the area. The suspect was spotted getting into a vehicle. A Precinct 4 deputy constable tried to stop him and that's when the suspect got out of the vehicle and fled on foot.
The suspect, Zumbotha Newsome, is wanted in connection with a fatal road rage case from April 15 in northwest Houston. That crime happened in the area of 34th Street and Bella Vista.
Newsome, 36, is described as a black male about 5-foot-9, 200 pounds, with a scar on his forehead. He also sports tattoos on his left and right arms. Newsome also goes by the alias Michael Ray Bunn.
"We're asking anybody if they've seen anybody about 5'9", 200 pounds, black male wearing black T-shirt and black shorts to go ahead and either call Crime Stoppers or call 911," said Alfredo Perez with the U.S. Marshals.
Perez says Newsome is considered armed and dangerous.
