Suspect in agent’s shooting named

CHULA VISTA, Calif. – Authorities in Mexico have named the man suspected of fatally shooting a U.S. Border Patrol agent.

Mexican federal police said Sunday the main suspect in the killing is 36-year-old Ernesto Parra Valenzuela.

Parra Valenzuela was detained on Friday and was reportedly carrying a Border Patrol-issued pistol at the time of his arrest.

Records show Parra Valenzuela had not retained an attorney Sunday.

Four other men suspected of involvement in the killing were detained Saturday.

Authorities wouldn’t say what role, if any, the other four men may have played in the death of Agent Robert Rosas, a 30-year-old father of two who was killed Thursday near the Mexican border in southeastern San Diego County.

Space station’s air purifier fixed

CAPE CANAVERAL, Fla. – A space station air purifier was working again Sunday after it shut down at the worst possible time, when company was still visiting and had swollen the on-board crowd to a record 13.

The machine for cleansing the station atmosphere, on the U.S. side of the sprawling outpost, failed Saturday when it got too hot and tripped a circuit breaker.

Flight controllers managed to get the unit up and running again 8 1/2 hours later in manual mode. That means extra people are needed in Mission Control to handle the approximately 50 computer commands that need to be sent up every few hours.

An air-cleansing system on the Russian side of the station is working fine. In addition, the station has about three weeks’ worth of canisters for removing the carbon dioxide exhaled by crew members.
