​The latest news article on the "middle child":

​The girl was one of four victims found in two barrels near Bear Brook State Park in Allenstown in 1985 and 2000. Three of them were identified last year as Marlyse Elizabeth Honeychurch and her two children, Marie Elizabeth Vaughn and Sarah Lynn McWaters. The unidentified girl isn't believed to be related to them.

The investigation suggests that the unidentified girl was not from New Hampshire, but most likely from Texas, Arizona, California or Oregon.

​Through ongoing genealogy work, the National Center for Missing and Exploited Children says the child is primarily Caucasian with a small amount of Asian, black and American Indian ancestry. She was 2 to 4 years old at the time of her death, placing her birthdate between 1975-1977. She had slightly wavy brown hair and stood as tall as 3 feet, 9 inches. She had a slight overbite.

Authorities believe Terry Peder Rasmussen was responsible for all four deaths and that the unidentified body is his daughter's. He went by many aliases, including "Bob Evans."

Rasmussen, who is suspected of killing at least six women and two children, died in a California prison in 2010.

Rasmussen claimed to spend substantial time in Texas during the early 1980s and may have known someone staying at an RV park in Austin during 1986. He claimed to have been employed at a company called Brown and Root in Houston during the 1970s.  

Attempts to reach relatives of Rasmussen have been unsuccessful.

Please contact the National Center for Missing & Exploited Children at 1-800-THE-LOST if you have any information that could help identify this child.

​​It is unclear how this child is associated with the three related females but it’s estimated that they all died at the same time between 1978-1984. Advanced forensic testing reveals that this non-related child did not grow up in the same geographic area as other three victims. She likely was born and spent the majority of her childhood in a more northern and inland location such as northern New Hampshire, northern Vermont, upstate New York and further inland.

Based on isotope testing this little girl likely lived in the highlighted areas in the late 1970's. 

​Her mother could have been from an area where Terry was living  under an alias (see graphic below timeline) and then moved with him giving birth in the destination area. 

According to a June 2019 interview with Terry Rasmussen's daughter she had met the unidentified "Middle Child". 

"While authorities have been unable to identify a fourth body found in the barrels, beyond figuring out that she was Rasmussen’s daughter, Stiers, the youngest of four children, said she and her siblings refer to their half sister as “Anita Moon.” She remembers meeting her; she doesn’t remember where. “I met her in somebody’s house,” she told the Union Leader. “She had pigtails on each side and they stuck straight out. … I remember her being cute and being shy. … She was adorable.”

Man suspected of beheading Washington woman found dead in California
POSTED 2:50 PM, APRIL 16, 2019, BY Q13 NEWS STAFF, UPDATED AT 03:16PM, APRIL 16, 2019

YUBA CITY, Calif. — A man suspected of using a samurai sword to kill his girlfriend in last year in Washington state was found dead in northern California.
According to the Island County Sheriff’s Office, a man’s body was pulled from the Feather River in Yuba City, California on April 7, 2018.
The body was classified as a “John Doe” until November when investigators shared photos of the man’s tattoos in hopes of identifying him.
Investigators with the Sutter County Sheriff’s Office received tips and this month were able to use DNA to positively identify the man as Jacob Gonzales.
Police in early March of 2018 found the body of 26-year-old Katherine Cunningham on an undeveloped piece of land near a gun- and ammo-filled bunker on Camano Island, Washington.

Authorities said a car belonging to Cunningham was found in northern California, also in early March. But police were not able to find him.
Island County Prosecutor Gregory Banks said a samurai sword was found in the vehicleand sent for testing at a lab.
“Those lab results indicate that Ms. Cunningham’s blood was on the blade of the sword, and Mr. Gonzales’ DNA was on the hilt,” he said.
Authorities had been seeking Gonzales since March on a warrant. He was previously charged with five counts of unlawful possession of a firearm and one count of motor vehicle theft.
According to court documents, Cunningham likely died in mid-February. Authorities said she might have been staying in a trailer on the property. Her body was found by a couple looking to buy the property.

15 to 45 year old White
Hispanic/Latino Female
Date found October 13, 2010

Circumstances: Unknown. Incomplete remains discovered by a civilian searching for mushrooms in a wooded area of Joint Base Lewis-McChord (exclusive federal jurisdiction).

​https://www.namus.gov/UnidentifiedPersons/Case#/9978

The US Army Criminal Investigation Command is offering a $15,000 reward for information about a Jane Doe found  in Training area 9 of Joint Base Lewis-McChord  Washington 98433 (Pierce County).

On October 13, 2010, the skull of an adult female, approximately 25-40 years old, was
discovered in the vicinity of Spanaway McKenna Highway (WA 507) and Pacific Avenue
South (WA 7) inside of Training Area 9. After an extensive search of the area by CID and
other law enforcement agencies, only a skull and several vertebrae were recovered at the
scene. The rest of the victim’s remains have never been found.

CID wants to stress the most identifiable and notable feature that may lead to the identity of the deceased is a defect of unknown origin on the victim’s front tooth on the lower jaw (pictured above). Although important, the facial reconstruction pictured above is a recreation based on all available forensic evidence and may not be an exact likeness of the deceased. The victim’s race is still unknown at this time, and it is possible that the victim could have been of a mixed ancestry. The Office of the Armed Forces Medical Examiner estimates the victim to have died between April and June of 2010. ​

The testing revealed the victim may have spent her childhood/adolescence and the last ten years prior to her death in Oregon or California.
