Brenda Joan Allen-Szabo, 33, was last seen October 1, 1983, in San Diego County, California. Her life before that date included long-term struggles with drug addiction and criminal involvement, several prison terms in the 1970s, frequent travel between New York and California, the use of multiple aliases and social security numbers, and four children she ultimately placed for adoption.

In the early 1980s Brenda was reportedly trying to change course: she enrolled in community college to study wildlife and forestry and worked as a dog groomer. She had recently been jailed for a probation violation and released. Brenda told family she planned to travel to Dallas, Texas, to visit and promised to call in two weeks, but she never made contact and has not been seen since.

Her disappearance only came to official attention in June 2005 when one of her daughters, searching for her birth mother, reported her missing. San Diego and San Bernardino County authorities have been unable to locate her. Does anyone have information about Brenda’s movements around October 1983 or recall her plans to travel to Dallas?
