Patricia Plummer Mondrik was found dead inside her apartment in the 9800 block of Powhattan on Tuesday, September 1, 1981. Her employer had been trying to reach her after she did not show for work on Monday; when she was discovered the following day, she appeared to have been dead for several days. Patricia suffered massive head and facial wounds and multiple stab wounds.

Investigators say evidence indicates Patricia knew her assailant. A boyfriend vanished immediately before the body was found, and investigators believe he fled to Mexico. Homicide detectives want to speak with him and are asking for any information or evidence that could help solve the case.

If anyone knew Patricia’s movements, associates, or the boyfriend who left town around the time of her death, can you provide information to homicide detectives?
