Ex-Girlfriend Helps ID Suspect in Little Village Jewelry Store Double Homicide
CHICAGO — In a chilling development to a Little Village double homicide that stunned the Southwest Side last fall, court records show that the man now charged with killing a father and son was identified by a former girlfriend after she saw his face in a television news report. The shocking twist in the investigation has given detectives a critical piece of evidence in unraveling one of Chicago’s most violent crimes of 2025.
The victims, 63-year-old Faustino Alamo and his 25-year-old son Luis Angel Alamo, were gunned down during a violent confrontation at their jewelry store on Nov. 8. They were trying to prevent a robbery at Angelo’s Jewelry when the shooting erupted, leaving both men dead and sending shockwaves through the tight-knit Little Village community.
The suspect at the center of the murder case is 35-year-old Muhammad Idris Thomas, also known as Mike Pekara, according to a court filing provided by prosecutors. Thomas was arrested by federal marshals earlier this year in St. Louis after an intensive search that spanned multiple states and several weeks of investigation — but the clues that brought him into custody came from an unexpected source.
Authorities had been piecing together the movements of a Maserati seen in surveillance footage from the jewelry store and examining phone data that tied multiple devices — including those of two juveniles believed to have been involved — to key locations connected to the crime. Forensic evidence from the store entrance also showed a DNA profile linking Thomas directly to the scene.
Despite these leads, investigators faced a challenge: identifying the driver of the Maserati. That’s when a former girlfriend of Thomas watched a news broadcast about the murders and immediately recognized him as the man in the video. She contacted authorities, providing a key eyewitness identification that matched Thomas to the crime. The court proffer notes that she positively identified him after seeing his image in the news.
The sequence of events that led to the fatal encounter at Angelo’s Jewelry began earlier on Nov. 8, when Thomas first arrived at the store around midday. Court documents show he entered the shop, spoke with Faustino and even tried on jewelry before leaving briefly. Later in the afternoon, Thomas returned, rang the door buzzer and was let inside by Luis Alamo.
According to prosecutors, Thomas placed a cellphone in the door frame to keep the door from locking behind him. When the phone fell and he bent to retrieve it, Luis Alamo pushed him, igniting a violent confrontation that spilled onto the street. Faustino, armed with a handgun, charged toward the struggle in a desperate attempt to protect his son.
Surveillance video and witness accounts show that Thomas then drew a handgun of his own and fired. He shot Luis in the leg, then fired additional rounds as Faustino advanced with his firearm. At the same time, one of the juveniles — described in court records as “juvenile co-offender 1” — fired a second weapon, striking Faustino. The two men collapsed, and Thomas sped off in the Maserati.
Several days after the killings, the two juveniles were arrested on unrelated charges. One served as a witness and helped confirm that Thomas was the driver seen in the Maserati at the scene. Law enforcement compared still photos from before and during the incident, and the witness identified both Thomas and the teen involved in the shooting.
Investigators also used data from eight cellphone pings tied to the Maserati and the juveniles, placing the devices at locations that aligned with the timeline of the crime, including the May visit to the jewelry store, the pickup location of the juveniles and the spot where the murders occurred. A search warrant for the Maserati’s infotainment system further corroborated its presence at all those critical sites.
For years, the Little Village neighborhood has wrestled with waves of violence and the fear that it brings to families and business owners. The shooting of the Alamos — a father and son known for running a beloved local business — only amplified community concerns about public safety and criminal justice. In November, the news of their deaths triggered an outpouring of grief as neighbors demanded answers and justice.
Thomas had managed to evade arrest for months before U.S. Marshals located him at a hotel in St. Louis in late January. When agents approached his room, they heard flushing inside — a sign that he may have tried to destroy evidence. Upon entry, they also found a pillowcase on a nearby rooftop containing two firearms and ammunition. Ballistics later confirmed that one of those guns matched a bullet casing found at the Little Village crime scene, and the second matched a separate casing recovered there.
Prosecutors have charged Thomas with first-degree murder in connection with both slayings, and his case will now proceed through the Cook County court system. The juveniles involved have not been charged in the slayings, but their roles and how the legal process will unfold for them remain under investigation.
The identification by the former girlfriend shows how sometimes seemingly small pieces of information — a face in a news broadcast — can tip the scales in a major criminal case. For the Alamo family, it has brought a measure of closure amid tremendous loss, though the emotional wounds of losing both a father and son in a senseless robbery-turned-homicide still run deep.
As Chicago’s legal system now prepares for a trial that could span months, family and friends of the victims are watching closely, hoping that justice will finally be served in a case that highlighted both the tragedy of violent crime and the perseverance of investigators piecing together every available lead.
