A man who was found guilty of first-degree murder for killing his own grandmother in her home in Westminster received a life sentence in prison on Monday (May 10).

As per reports from 9News, 25-year-old John Swenson was convicted nearly two weeks ago of the murder of his grandmother, 75-year-old Linda Shomberg after a four-day trial in an Adams County courtroom.

On Dec. 9, 2019, Westminster police responded to an apartment at a senior housing center on 68th Avenue when Shomberg's daughter called to report that she was concerned because she hadn't been in contact with her mother Linda in several days, according to prosecutors.

When officers arrived on scene at the apartment, they found the 75-year-old woman lying on the floor. She was bleeding from her head and was unresponsive, as per a news release regarding the incident, and later died at a hospital.

Prosecutors in the case said Shomberg had suffered severe injuries to her face, skull and brain as a result of significant blunt force trauma.

Her grandson, John Swenson had been staying with his grandmother in her Westminster apartment after being forced to leave a halfway house, the news release noted. Shomberg's neighbors reported to police that three days before her body was discovered, they had continuously heard loud, pounding noises coming from her apartment.

The medical examiner on the case later concluded that Shomberg suffered a stroke and that the assault and blunt-force trauma to her head contributed to her death.

“This brutal crime shocks the conscience,” Adams County District Attorney Brian Mason said.  “The defendant’s brutality against his own grandmother was truly unspeakable.  I appreciate the jury returning a just verdict in this case.”
