KEY POINTS:
DENVER - Officials evacuated a high school in Parker, Colorado, after an explosion outside today, the eighth anniversary of a massacre at nearby Columbine High School.
There were no injuries in the blast behind Ponderosa High School, according to Douglas County Sheriff's Deputy Cocha Heyden. She said officials caught a suspect who was carrying another explosive device.
"At this time it has not been determined what the device was," Heyden said.
The school blast came on the anniversary of the 1999 Columbine shooting in which two students killed 13 people in Littleton, Colorado. Both Parker and Littleton are suburbs of Denver.
The incident was the latest in a series of scares after Virginia Tech student Cho Seung-Hui shot and killed 32 people and himself on the Blacksburg, Virginia, campus on Monday in the deadliest shooting rampage in modern US history.
In Arizona on Friday, police evacuated part of the state Capitol after a bomb threat there, authorities said.
State Capitol spokesman Alan Ecker said officers evacuated the state Senate, House and governor's tower in central Phoenix after the early morning threat was telephoned in.
The evacuations followed others in California on Thursday.
In Northern California, a man who threatened to go on a killing spree inspired by Monday's Virginia Tech murders turned himself over to police on Thursday night.
Before Jeffery Thomas Carney turned himself in, schools in Yuba City and Marysville north of the capital, Sacramento, went into lockdown and said they would stay closed on Friday.
