On October 8, 1974, 24-year-old Martha Ann McClendon was among five members of her family murdered at the Riverside Village apartment complex in Fort Worth, Texas. Martha, who worked as a machine helper at a furniture manufacturing company, had been visiting her sister Laura, their cousin Linda and the children Natasha and Steven when 23-year-old acquaintance Kenneth Granviel arrived uninvited. Money was taken from the victims before the attacker fled.

Two Mexican nationals were initially arrested but later shown not to be responsible. Granviel, who had been dishonorably discharged from the military and had a history of violent behavior, was not immediately suspected; he was arrested months later after committing additional attacks and confessed to these killings. Anyone with memories of the Riverside Village complex or the victims is asked to share what they know.
