U.S. Attorney General Jeff Sessions is considering reopening the investigation into the murder of Emmett Till, one week after he met with relatives of the 15-year-old who was brutally killed in Mississippi in 1955 and whose death gave momentum to the civil rights movement.

Sessions "said no one gets a pass," recounted Till's cousin, Deborah Watts, who met with the attorney general and ex-Alabama senator last week. During the meeting, Sessions also gave his support for legislation that would allow the Justice Department to pursue civil rights cold cases before 1980, according to the Jackson Clarion-Ledger.

Till, a black 15-year-old from Chicago who was visiting family in Mississippi, was beaten and killed by two white men -- Roy Bryant and his half-brother, J.W. Milam, -- after one of the men's wives -- Carolyn Bryant Donham -- said Till wolf-whistled at her and touched her in a convenience store her husband owned.

Till's body was found three days later in the Tallahatchie River with a 75-pound cotton gin fan tied around his neck. The case garnered international attention after Till's mother had his body displayed in an opened casket so the world could see how her son suffered.

Bryant and Milam were acquitted by an all-white Mississippi jury, and then confessed to the murder a year later.

The Justice Department is considering reopening the case because Carolyn Bryant Donham admitted she lied about Till touching her -- although an all-black grand jury in Mississippi chose not to indict her when the FBI reopened the case in 2004.
