美国纽约州警察星期二继续搜捕两名被定罪的杀人犯，之前有人看见他们星期一夜间冒雨在一条公路步行。
几十名持枪警察星期三在纽约州威尔斯伯罗镇附近的农场和田地搜捕越狱潜逃的大卫·斯威特和理查德·马特。当局认为这两人上星期从靠近加拿大边界的丹尼莫拉镇高度警戒的监狱越狱后徒步逃亡。
警方说，斯威特和马特使用电动工具从牢房一直挖掘到附近大街的地下管道，然后从出口逃出。
人们对此提出疑问：犯人如何获得电动工具以及为什么噪音没有引起监狱看守和其他犯人的注意。
斯威特2002年因杀死一名警长而被判处无期徒刑。马特1997年杀死一名男子后被控谋杀、绑架和抢劫，被判处25年监禁。
纽约州州长安德鲁·科莫说，这两人得以越狱一定得到了其他人的帮助。
Police in New York state searched Tuesday for two convicted killers after they were reported walking along a road in a driving rainstorm the night before.
Dozens of police armed with rifles walked through farms and fields near the town of Willsboro as they tried to apprehend David Sweat and Richard Matt.
Authorities believe the two men are on foot after a daring escape last week from a maximum security prison farther north in Dannemora, located near the Canadian border.
Officials say Sweat and Matt used power tools to carve out their escape route from their cells to a manhole cover in a nearby street.
Questions have been raised about how the inmates obtained the tools, and why the noise did not draw the attention of prison staff or other inmates.
Sweat was serving a life sentence for the 2002 death of a sheriff's deputy. Matt faced 25 years to life in prison on murder, kidnapping and robbery charges following the 1997 killing of a man.
New York Governor Andrew Cuomo said the duo "definitely had help" in their escape.
