A Wisconsin man has been charged with killing his wife more than a year after she mysteriously disappeared, even though investigators still have not found her body. Authorities say evidence collected during the lengthy investigation led prosecutors to file homicide charges against the husband, who is now being held on a $1 million cash bond.
The case has gained major attention because of the unusual evidence involved, including alleged domestic abuse claims, suspicious online activity, blood evidence, and the use of cadaver dogs during searches.

Woman Disappeared More Than a Year Ago
According to investigators, Alexis Nelson was last seen in May 2025.
Authorities say the Dodge County Sheriff’s Office and Beaver Dam Police Department spent several months quietly investigating her disappearance before publicly asking for help in early 2026.
Police later announced that Aaron Nelson had been arrested and formally charged with:
- First-degree intentional homicide
- Hiding a corpse
Despite the charges, officials confirmed Alexis’ remains have still not been found.
Investigators Point to History of Domestic Problems
Prosecutors allege that the marriage between Aaron and Alexis Nelson had become troubled before her disappearance.
According to reports, Alexis had previously accused her husband of abusive behaviour and had filed for a restraining order after an alleged domestic violence incident.
Authorities believe the alleged history of abuse became an important part of the homicide investigation.
A neighbour who lived near the couple’s apartment reportedly told investigators they often heard arguments coming from the home before Alexis disappeared.
Surveillance and Phone Records Became Key Evidence
Investigators say surveillance footage captured the couple together at a Kwik Trip convenience store in Beaver Dam on March 29, 2025.
According to the criminal complaint, this was one of the last confirmed sightings of Alexis.
Authorities also reviewed cellphone records, which allegedly showed Alexis’ phone later travelling toward Sun Prairie, Wisconsin.
Police claim Aaron Nelson then purchased a 32-gallon trash can the following day, which investigators later considered suspicious.
New Facebook Account Raised Questions
Prosecutors also pointed to unusual behaviour after Alexis disappeared.
According to reports, Aaron Nelson allegedly created a new Facebook account under the name “James Nelson” shortly after his wife vanished.
Investigators said the account listed his relationship status as “widowed,” despite Alexis never being officially declared dead.
Authorities believe this activity raised additional suspicion during the investigation.
New Relationship and Wedding Ring Discovery
Investigators also alleged that Nelson quickly entered a new romantic relationship after his wife disappeared.
According to reports:
- He allegedly met another woman on Tinder in April 2025
- He reportedly moved in with her within weeks
During the investigation, detectives noticed the woman was allegedly wearing Alexis Nelson’s wedding ring.
That discovery reportedly became another major focus for investigators.
Blood Evidence Found in Trash Can
One of the most important developments came during a search of the girlfriend’s property.
Authorities executed a search warrant at the residence in June and reportedly found the same type of 32-gallon trash can investigators believed Nelson had purchased earlier.
According to reports, forensic testing later showed the trash can contained Alexis Nelson’s blood.
Investigators also used a cadaver dog during the search. Authorities said the dog alerted to a shed where the trash can had reportedly been stored.
No Body Found, But Charges Filed
Even though Alexis Nelson’s body has not been recovered, prosecutors still moved forward with homicide charges.
In many criminal cases, authorities can file murder charges without finding remains if they believe enough evidence exists to show a person is dead and that another person caused the death.
Investigators noted that there has been:
- No official record of Alexis being alive
- No activity proving she voluntarily disappeared
- No documentation of her death through normal legal processes
Police say the overall evidence led prosecutors to believe homicide charges were justified.
Court Appearance Scheduled
Following his arrest, Aaron Nelson appeared before a judge, who set his bond at $1 million cash.
He remains in custody at the Dodge County Jail.
Court records show his next scheduled court appearance is set for May 28.
Case Highlights Challenges in ‘No Body’ Investigations
Cases where murder charges are filed without a recovered body are often among the most difficult investigations for prosecutors.
Authorities usually rely heavily on:
- Digital evidence
- Blood and forensic testing
- Witness statements
- Surveillance footage
- Behaviour after the disappearance
This Wisconsin case has drawn attention because investigators spent more than a year building evidence before making an arrest.
