In Boston, Pictou began to meet urban American Indians and other First Nations people from Canada. About 1968–1969, she met members of the
American Indian Movement (AIM), founded in Minneapolis in 1968. They were organizing among urban Indians, initially to combat police discrimination and brutality against their people. Pictou became involved in the Teaching and Research in Bicultural Education School Project (TRIBES), a program in Bar Harbor, Maine to teach young
American Indians about their history. On Thanksgiving Day 1970, AIM activists in Boston held a major protest against the
Mayflower II celebration at the harbor by boarding and seizing the ship. In 1973, Nogeeshik and Anna Mae traveled together to the
Pine Ridge Indian Reservation in South Dakota to join AIM activists and
Oglala Lakota in resistance to internal issues. Federal law enforcement became involved in what developed as the activists' 71-day
occupation of Wounded Knee, which ended on May 8, 1973. Using the surname Aquash, in 1974 Annie Mae was based mostly in Minneapolis. She worked on the Red Schoolhouse project, for a culturally based school for the numerous American Indian students who lived in the city. That year she also participated in the armed occupation at Anicinabe Park in
Kenora, Ontario by
Ojibwe activists and AIM supporters. They were protesting treatment of the Ojibwe in Kenora and northwestern Ontario in relation to health, police harassment, education and other issues, and failures by the national government's Office of Indian Affairs to improve conditions. Aquash also continued to work for the Elders and Lakota People of the
Pine Ridge Indian Reservation. The Catholic abbey had been closed and abandoned, and the Menominee wanted the property returned to the tribe, as the land had originally been appropriated by the Alexian Brothers for their mission. Leaders were nervous since they had discovered on March 12, 1975, that
Douglas Durham, a prominent member who by then had been appointed as head of security for AIM, was an FBI informant. The officials expelled him from AIM in March 1975 at a public press conference. When Banks went into hiding, Aquash and
Darlene (Ka-Mook) Nichols joined him at various times in late 1975 as he, along with Peltier and others, moved throughout the West for several months in an
R.V. lent by actor
Marlon Brando, an AIM sympathizer. According to Ka-Mook Nichols, while camping in Washington in October 1975, Peltier bragged to her, Annie Mae and others about shooting the two FBI agents on June 26, 1975. On November 14, 1975, while they were heading south through Oregon, a state trooper pulled over the R.V., full of guns and explosives, and ordered everybody out. Peltier and Banks escaped, but Kenny Loud Hawk, Russ Redner, Aquash, and others were taken to jail. After having spent ten days in jail, Annie Mae Aquash was released on bail in
Pierre, South Dakota on November 24. A couple of days later, she went to stay at the home of Troy Lynn Yellow Wood-Williams in
Denver, Colorado. After having been seen in Denver and Rapid City, South Dakota for the last time
on December 11, she disappeared in mid-December 1975. ==Murder==
