Not all the news in 2025 was good news.
As in any year, there were also some unfortunate, and even tragic, events in the area.
Below is a look at some of the charges filed and sentences handed down over 2025 in and around Butler County.
Four deceased infants were found Sept. 13 in Jessica Mauthe’s home in Cadogan Township, Armstrong County.
Investigators determined the infants were all born in the last six years, with the most recent being born about a year and a half ago, according to state Trooper Greg Durick’s testimony at an Oct. 28 preliminary hearing.
Mauthe, 39, is awaiting a pretrial conference before her next court date will be scheduled, according to her court docket. She’s being held in the Armstrong County Jail.
Butler County witnessed two murder-suicides in 2025 — one in Jackson Township and another in Butler.

Platt died by suicide, police said.
Just more than a month later on May 28, Beth Broeren was strangled in her home on Cottage Hill Avenue in Butler by Alfredo Diaz, with whom she was living, according to police. They were both 66 years old.

Keith Randall Smith, 69, of Cranberry Township, has been recently charged in eight criminal cases stemming from his business practices at Oilology, a Cranberry Township car maintenance service.

A jury found Michael shot Derenzo six times in Michael’s townhome and a nearby garage for the second homicide on Spooner Drive in Butler Township within two years.
The district attorney’s office sought a first-degree murder conviction with a death penalty or life in prison, but the charge was reduced to third-degree murder with a maximum penalty of 40 years. Michael had previously testified he was acting in self-defense.
Michael is being held in a state correctional institute in Cumberland County.
