Normal, Illinois - February 17, 2026 - Michael Cosgrove, 41, of Illinois, has been formally charged with first-degree murder in the death of his ex-wife, Tammy Cosgrove, 41. The tragic incident, which unfolded in Normal, Illinois, has sent shockwaves through the community and once again highlights the devastating reality of domestic violence, even after legal separation.

Tammy Cosgrove was discovered deceased in her home on Monday, February 15th, prompting a swift response from the Bloomington-Normal Police Department. Michael Cosgrove allegedly contacted 911, reporting that he had found Tammy unresponsive. Upon arrival, officers found Michael waiting outside the residence and promptly took him into custody. He remains held without bail as of today.

According to a police press release, the initial 911 call and subsequent investigation quickly revealed inconsistencies, leading detectives to suspect foul play. "Based on evidence collected at the scene and subsequent investigation, Michael Cosgrove was charged with first-degree murder," a police spokesperson stated. The specifics of the evidence are currently being withheld to avoid compromising the ongoing investigation and potential trial.

Cosgrove is slated to appear in court on February 18th, where he will formally enter a plea. If convicted of first-degree murder, he faces a substantial prison sentence ranging from 20 to 60 years. The McLean County State's Attorney's Office is leading the prosecution, and legal experts predict a complex and emotionally charged trial.

A History of Separation & Legal Battles

Court records reveal a tumultuous separation between the Cosgroves. Tammy filed for divorce in McLean County in August 2023, citing irreconcilable differences. The divorce was finalized in December 2023, bringing a legal end to their marriage, but, tragically, not an end to the conflict. While the specifics of the divorce proceedings remain sealed, sources close to the family suggest disputes over property and potentially spousal support contributed to ongoing tensions.

This case underscores a concerning pattern: a significant percentage of domestic violence incidents, and unfortunately, fatalities, occur after a separation or divorce has been initiated. The power dynamics within a relationship often shift dramatically during this period, creating a volatile environment where abusers may feel a loss of control, leading to escalated violence. Advocacy groups specializing in domestic violence have long warned of the increased risk during these transition periods.

The Growing Crisis of Domestic Violence

The Cosgrove case is not isolated. Domestic violence remains a pervasive problem across the United States, affecting individuals of all ages, genders, and socioeconomic backgrounds. National statistics indicate a worrying trend of increasing reported cases, compounded by the pandemic's isolating effects and the economic stressors that followed. Resources for victims are often stretched thin, and access to mental health support and legal aid remains a significant barrier for many.

Local organizations in the Bloomington-Normal area, such as the YWCA and PATH (Prevention of Abuse and Trauma in Homes), offer vital services to victims of domestic violence, including emergency shelter, counseling, and legal advocacy. These organizations are bracing for an increased demand for their services following this tragic event.

Looking Ahead: Legal Challenges & Victim Support The McLean County State's Attorney's Office faces the challenge of building a strong case against Michael Cosgrove. Prosecutors will likely focus on presenting forensic evidence, witness testimony, and a comprehensive timeline of events leading up to Tammy's death. The defense will undoubtedly scrutinize the evidence and raise questions about the circumstances surrounding the discovery of the body.

Beyond the legal proceedings, the focus must remain on supporting the family and friends of Tammy Cosgrove. Grief counseling and victim assistance programs are crucial in helping them navigate this devastating loss. It's also imperative that this tragedy serves as a catalyst for raising awareness about domestic violence and encouraging individuals to seek help if they are experiencing abuse or know someone who is.
