DENVER -- Sources told 7NEWS Wednesday that an earlier story about inconclusive blood tests in a missing mother and daughter case is not accurate.

Watch Michael Blagg's Appeal For Information About His Family

The Grand Junction Sentinel reported Wednesday that a full DNA analysis of the blood could not determine if the blood came from Jennifer Blagg, 34, her 6-year-old daughter Abby (pictured, left), or someone else.

A source close to the investigation told 7NEWS reporter Julie Hayden, however, that the test results helped investigators "clarify some issues" and is giving a "focus" to the investigation.

"We cannot yet rule out that the blood does not belong to one of the missing people," Mesa County sheriff's spokeswoman Janet Prell said Wednesday.

While the results of the blood test haven't been disclosed, Hayden said sources told her that the evidence indicated the blood is probably from one person.

Michael Blagg reported his wife and daughter missing from the family's home on the afternoonn of Nov. 13. He said he last saw his wife before he left for work.

Abby Blagg did not show up for school that day, and Jennifer Blagg's car was still in the garage that afternoon. That indicates the two disappeared sometime after Michael said he left for work and the start of Abby's first class.

Blagg arrived home to find a large pool of blood on the bed in the master bedroom. Samples of that blood are undergoing additional analysis by the Colorado Bureau of Investigation in Montrose, Colo.

Sources told 7NEWS no other blood pools, or blood drops, were found in the house, which was a significant indication of what may have happened to the bleeding person.

Results from more thorough tests on the blood are expected early next week.

Numerous searches of the area around the Blagg home, including the nearby Colorado River, have failed to turn up any trace of the mother and daughter. Searchers planned to probe the river again later this week.

Investigators said previously that Michael Blagg is not a suspect in the case but now say they haven't ruled anyone out at a suspect.
