EL PASO, Texas — A 76-year-old former school teacher has been sentenced in West Texas to 45 years in prison for the death of her estranged Green Beret husband in 1977.
An El Paso County jury deliberated for almost two hours before sentencing Lisbeth Garrett on Thursday, a day after jurors found her guilty of murdering Fort Bliss Army Maj. Chester Garrett.
Trial testimony focused on a blood stain found in the home where prosecutors say Chester Garrett was killed. Prosecutors also argued that Lisbeth Garrett stood to benefit financially from her estranged husband’s death, the El Paso Times reported.
Roger Garrett, the son of Lisbeth Garrett from another relationship, was convicted of murder in 2013 in the major’s death and sentenced to 40 years in prison.
Authorities had reopened the cold case when Roger Garrett’s stepbrother, Patrick Garrett, provided new information.
Patrick Garrett testified against his mother during her trial, telling jurors that at the time of his father’s death he and his stepbrother used acid to clean a “giant red Kool-Aid stain” in their garage, the newspaper reported. Authorities have said that he previously told them that Robert Garrett confessed in 1990 to the killing.
