For four decades, police detectives have been vexed by a mystery about two bodies found in oil fields off Calder Road, one in 1986, another in 1991.
The women — two among four bodies found in the field over a seven-year period — have long been known as Jane and Janet Doe.
The League City Police Department said Thursday those pseudonyms no longer were needed — the Calder Road bodies had been identified.
Police, however, would not release the names of the women Thursday.
The department plans to hold a news conference Monday to reveal the identities and discuss the progress of the case.
The department is delaying release of the names so that national news organizations can learn about and attend the conference, police department spokesman Kelly Williamson said.
“As this is a story of national interest, we wanted to give those out-of-town media outlets time to muster and make the trip if they choose to do so,” Williamson said.
No arrests have been announced in connection to the latest developments in the investigations.
With the knowledge of who the women are, however, investigators can trace their histories and possibly connect their movements and contacts with suspects or persons of interest, an investigator not involved in the case said.
In December, the police department released digital composite images of the two women and asked for the public’s help in identifying them. The composites were created by a Virginia company that uses DNA phenotyping — the use of biological material to determine physical characteristics — to make the images.
The DNA testing found that one of the women was likely from Tennessee and the other from Louisiana. They were both likely white and in their 20s or 30s, police said.
In late December, investigators said the DNA testing had identified some distant relatives of the victims, and that they were working on narrowing down those family trees to identify the women.
The two women are part of a group of bodies found near Calder Road that have led the area to become known as the Texas Killing Fields.
No one has ever been convicted in connection with the bodies found in the Calder Road field.
Authorities in 2014 said they suspected a San Leon man was involved in the killings, however.
Clyde Hedrick was convicted of manslaughter in the death of Ellen Rae Beason. Before Hedrick went to trial, prosecutors said they could seek to link him to the deaths of two other women found dead in the fields, Heide Fye and Laura Miller.
That connection was never made in Hedrick’s trial, and Hedrick has not been charged with additional crimes since he was convicted, according to Galveston County court records.
