向奧巴馬投寄帶毒信件的嫌疑人被逮捕大綱
U.S. investigators say a suspect in Mississippi has been arrested in connection with a poisoned letter sent to U.S. President Barack Obama.
The FBI said suspect Paul Kevin Curtis was arrested Wednesday in Corinth, Mississippi. Investigators did not provide further details.
However, an FBI intelligence bulletin seen by reporters said the suspect April 8 letter to Mr. Obama and a second one addressed to U.S. Senator Roger Wicker were postmarked in Memphis, Tennessee and contained some identical wording.
Both letters preliminarily tested positive for ricin, a highly poisonous chemical compound that is deadly in amounts as small as a grain of salt.
Investigators said both letters were intercepted at mail screening facilities away from the White House and Senate offices and consequently did not place either the president or the senator in immediate danger.美國調查人員說，在密西西比州逮捕了一名與寄給奧巴馬總統帶毒信件事件有關的嫌疑人。
美國聯邦調查局說，嫌疑人柯蒂斯星期三在密西西比州的科林斯被逮捕。調查人員沒有透露更多細節。
但記者看到的一份聯邦調查局情報簡報說，4月8號寄給奧巴馬的帶毒信件和寄給韋克爾參議員的帶毒信件上的郵戳顯示寄出地點是田納西州的孟菲斯，而兩封信件中的某些措辭完全一樣。
這兩封信件都初步檢測出帶有蓖麻油毒素，這是一種毒性極強的有毒化學制劑，極少量即可致命。
調查人員說，這兩封信件分別被白宮和參議院的信件檢查機構截獲，因此沒有對奧巴馬總統和韋克爾參議員構成威脅。
