A 25-year-old Missouri man was arrested last week for the murders of his estranged wife and their unborn son.

Sidney Fredrick Wilson V was charged on Thursday with first-degree murder in the deaths of Reagan Lynn Wilson, 21, and their son, Silas, according to the Lebanon Police Department. He faces additional charges for armed criminal action.

Lebanon police reported responding to Reagan Wilson’s residence around 11:30 p.m. on June 5, where they discovered her with several gunshot wounds. Although the baby initially survived the shooting, he passed away eight days later.

The heavily redacted probable cause statement obtained by the Springfield News Leader indicated that Wilson told officers he had reached his home around 8:30 p.m. on June 5. He received a call about the incident while at home and subsequently drove to the hospital after 12:30 a.m. Additionally, he mentioned receiving a Facebook message from Reagan Wilson hours prior, stating she “didn’t want him or his family there,” which upset him and led him to delay his response.

During their investigation, detectives found surveillance footage from Reagan Wilson’s house that captured a man resembling her estranged husband lurking around the premises shortly before 11:30 p.m.

Footage from surveillance cameras at Wilson’s residence supported his account initially, showing his claimed arrival and movements, including taking his dogs out. However, once his phone was searched, discrepancies emerged. Google Maps data revealed he departed his home around 10:30 p.m. on June 5, traveling toward Lebanon on Interstate 44, where Reagan Wilson resided. The data temporarily stopped “as if the location tracking was manually disabled,” resuming near Mercy Lebanon hospital at approximately 1:01 a.m. on June 6, 2025.

Further analysis of Wilson’s cell phone data placed his phone near his estranged wife’s residence at the time of the shooting and tracked its movement along Interstate 44 in Lebanon. The phone connected to nearby cell towers for about 40 minutes before leaving the vicinity and heading back toward Wilson’s home, eventually making another trip to the hospital.

“It should also be noted that while reviewing S. Wilson’s Wyze camera footage, a noise can be heard outside of his residence at 0013 hours on June 6, 2025, and the dogs ran through the dog door to go outside,” the affidavit says.

Investigators also found fingerprints on the outside of Wilson’s bedroom window.

Detectives also noted that Wilson “never once asked about the status of the investigation and where we were on locating a suspect in the investigation, he only asked about when he could get his vehicle back,” the affidavit said.
