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, the Lebanon Police Department said. He has also been charged with armed criminal action.

Lebanon police said they were called to Reagan Wilson’s home at about 11:30 p.m. on June 5 and found her with multiple gunshot wounds. The baby survived the initial shooting but died eight days later.

According to a heavily redacted probable cause statement obtained by the Springfield News Leader, Wilson told police he arrived at his home at about 8:30 p.m. on June 5 and was there when he got the call about the shooting and left to drive to the hospital shortly after 12:30 a.m.. He also told investigators that he had gotten a Facebook message from Reagan Wilson several hours earlier telling him that she “didn’t want him or his family there.” He admitted that the message upset him, saying that for that reason “he waited a while to respond back.”

As detectives investigated, they discovered surveillance footage from Reagan Wilson’s home that showed a man resembling her estranged husband creeping around her home just before 11:30 p.m.

Surveillance cameras at his home appeared to corroborate the timeline of his story, however, showing him arriving when he said he did and going inside, only emerging to take his dogs out. But once he allowed a search of his phone, the story began to unravel. Google Maps data from his phone showed that he had left his home at about 10:30 p.m. on June 5 and was traveling toward Lebanon, where Reagan Wilson lived, on Interstate 44. But the data suddenly stops “as if the location data was manually shut off and comes back on showing near Mercy Lebanon (hospital) at approximately 0101 hours on June 6, 2025.”

Further investigation of Wilson’s cell phone data showed his phone near his estranged wife’s home around the time of the shooting and traveling down Interstate 44 in Lebanon. The phone pinged off cell towers near her home for about 40 minutes then leaves the area and heads back toward Wilson’s home. Then, the phone leaves his home again and heads toward 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.
