Theodore Jacqueney, 36, a coordinator of Democracy International and associate editor of Worldview magazine, was found shot to death Wednesday at his home in West New York, N.J.

The circumstances of the death still are under investigation, according to West New York police officials.

A free-lance journalist, concerned with human rights, Mr. Jacqueney had served in Vietnam in 1969-70 as a community development and political officer for the Agency for International Development. He was assigned to Civil Operations and Rural Development.

He was in Washington in the early part of 1971 when he and several other AID employes who had served as advisers in Vietnam resigned from AID to protest this country's support for the government of South Vietnam President Thieu.

The group formed the Vietnam Elections Project here. Mr. Jacqueney remained in Washington as a free-lance writer until 1974, when he joined the Daily Journal in Elizabeth, N.J. He became associated with Worldview a year later.

He had traveled back to Southeast Asia and at one time also had visited political prisoners in Cuba.

Mr. Jacqueney was born in New York City. He graduated from the University of California at Berkeley and held a master's degree from Stanford University.

He is survived by his wife, Victoria, of the home; his parents, Mr. and Mrs. Theodore Jacqueney, of Long Beach, N.Y., and two sisters, Joan of New York City, and Stephanie, of Long Beach.
