[1] The arms and one thigh of the victim were discovered the following day, April 13, floating against the lock system of Willamette Falls in similar burlap packaging; both the hands and foot had been severed from the limbs and were missing.

In July 1946, the second thigh was found in the Willamette near Oregon City, and additional women's clothing believed to be that of the victim was recovered from the Clackamas River around the same time.

Though initially reported to have been a female in her late teens or twenties, a pathologist from the University of Oregon medical school confirmed the victim was a middle-aged caucasian woman between 40 and 50 years old.

The case received national media attention, appearing on the front page of numerous news outlets, but her identity and killer remain unknown.

[6] Two fishermen made the discovery, and told authorities they had noticed the burlap package floating in the area at least 30 days prior, but did not immediately find it suspicious.

[6] However, after reading of the discovery of the torso downstream, they returned to the area and found the package still floating against the falls' lock system, after which they notified law enforcement.

[9] The following month, on October 13, 1946, a package containing the woman's severed head was found near the location her torso had been discovered[2][10] by a married couple from Oak Grove.

"[5] Dr. Warren Hunter, a pathologist from the University of Oregon medical school,[14] subsequently examined the torso, and determined it belonged to a female "past middle age...about 50.

[6] Prior to the Hunter's analysis, national newspapers had reported the coroner's estimation that the victim was in her "teens or early twenties," resulting in a barrage of phone calls to law enforcement from concerned parents.

[20] In a 2017 interview with Clackamas County Sheriff’s Office Sergeant John Krummenacker, it was revealed that evidence in the case—including the location of the woman's clothing, jawbone, dentures, and other remains—were unknown.

[22] In April 1946, around the time the body was discovered, The Oregonian ran a notice seeking Anna Schrader, who had disappeared; she had previously told friends she was considering moving to Minnesota, but as of 2017, no public records of residence or her death are known.
