A man and a woman suspected of taking part in a shooting attack that killed 14 people and wounded 17 at a California social services agency on Wednesday died in a shootout with police hours later, authorities said.
据权威报道，周三发生的加州社会服务机构枪击案中有14人遇难，17人受伤，在案件发生几小时后，警方击毙了一男一女两名持枪歹徒。
One police officer was injured in the gunfight with the two suspects, who were confronted in their getaway vehicle after fleeing the scene of the shooting in San Bernardino, about 60 miles (100 km) east of Los Angeles.
歹徒在圣贝纳迪诺作案后驾车逃离现场，在距洛杉矶东约60英里（100公里）的地方被一名警官拦截，该警官在与两名歹徒的枪战中受伤。

Authorities also detained an individual seen running away from the vehicle, but investigators were not immediately sure that person was involved in the case, Police Chief Jarrod Burguan said at a news conference.
警长Jarrod Burguan在新闻发布会上称,警方还扣留了从车里跑出来的一个人，但是调查员还不能马上确认此人与案件有关。
The chief added he knew of no possible motive for the shooting spree, which unfolded at 11 a.m. on the campus of the Inland Regional Center, an agency that serves the developmentally disabled.
警长还补充道，目前对这起在上午11点在一家叫“内陆”社区中心展开的突发性枪击案件的动机尚不明确，这个机构是为残障人士服务的。
The shooting rampage marked the deadliest U.S. gun violence since the massacre at Sandy Hook Elementary School in Newtown, Connecticut, in December 2012, in which 27 people, including the gunman, were killed.
这次枪击暴行是自2012年12月在康涅狄格州新镇的桑迪胡克小学大屠杀以来，最血腥的枪击案。在那次的案件中包括歹徒共有27人丧生。
The Los Angeles Times, citing information from a senior federal official who was monitoring the case, reported that investigators believe one of the shooters left the party after getting into an argument and returned with one or two armed companions.
洛杉矶时报引用了在监控此案件的一个高级联邦官员的信息，称调查员们相信因为歹徒内部发生了争吵，有一个歹徒离开了团伙，并带了一个或是二个全副武装的同伴返回。
The police chief said he was aware that someone left the party following some kind of dispute but did not know whether that individual returned.
警长称他知道在发生了某些分歧后有人离开了团伙，但不清楚他是否还会返回。
