Two die in NASA standoff
A gunman killed himself and a male hostage while holed up in a barricaded building at NASA's Johnson Space Center, police say. Houston Police spokesman Capt. Dwayne Ready said a female hostage survived the ordeal. It is not know what, if any, relationship the killer had with his hostages. Houston police and NASA security were called about 1:40 p.m. CT and quickly surrounded Building 44, where work focuses on the engineering end of tracking spacecraft.
