How Was Alex Pennig Found? The Discovery and Initial Police Response
The discovery of Alex Pennig’s body in her bathroom triggered a rapid response from St. Paul Police, whose first impressions at the scene would prove pivotal. Examining the 911 timeline, crime-scene observations, and agency involvement illuminates the early investigative challenges.
What Happened on December 16, 2022?
At 7:48 a.m., a neighbor called 911 after noticing Pennig’s front door ajar and no response to repeated knocks. Officers arrived three minutes later and found Pennig unresponsive on the bathroom floor. This prompt timeline enabled preservation of forensic evidence that ultimately contradicted initial statements.
What Did Officers Observe at the Bathroom Crime Scene?
Officers noted several critical details:
- The door was slightly open with a metal fragment on the tile floor.
- Pennig’s body was positioned facing the doorway with gunshot residue on her clothing.
- The bathroom mirror and counter showed no signs of a struggle.
These observations shifted focus from accidental discharge or suicide to possible homicide, setting in motion specialized forensic analysis.
Which Law Enforcement Agencies Were Involved?
Two primary agencies collaborated on the investigation:
- St. Paul Police Department Homicide Unit led the scene processing and interviews.
- Minnesota Bureau of Criminal Apprehension (BCA) Forensic Lab conducted ballistic, residue, and DNA testing.
The joint effort combined local scene expertise with advanced laboratory techniques, advancing the inquiry from initial hypotheses to conclusive evidence.
Who Is Matthew Ecker? Suspect Profile and Initial Statements
Matthew Ecker was identified early on as the person present when Pennig was shot, and his account would become the focal point for detectives. Profiling Ecker and examining his statements highlight the discrepancies exposed by forensic evidence.
What Was Matthew Ecker’s Account of the Incident?
Matthew Ecker claimed he arrived at Pennig’s apartment around 7 a.m. to help with household chores and heard a loud noise while in the living room. According to Ecker, he rushed to the bathroom door, found it locked, forced it open, and discovered Pennig lying on the floor. He reported touching the door frame to break it open, which he said explained any fragments found.
How Did Matthew Ecker Know Alex Pennig?
Ecker and Pennig became friends through mutual colleagues at the hospital five years earlier. Their relationship involved occasional social outings and shared shifts. Understanding this friendship clarified why Ecker was in her apartment that morning and established a timeline for investigators to verify phone records and witness statements.
What Was Matthew Ecker’s Legal Status Following the Shooting?
After overnight interviews, Ecker was arrested the next day on suspicion of second-degree murder. He was formally charged in January 2023 and remained in custody pending trial. This legal status shifted focus from initial scene processing to courtroom preparation, where forensic evidence would become central to prosecution strategy.
What Forensic Evidence Solved the Case? Key Findings from the Bathroom Shooting
A combination of physical fragments, residue tests, DNA swabs, and blood-spatter patterns dismantled Ecker’s narrative and pinpointed the shooter’s actions. These findings demonstrate how forensic science transformed a contested statement into conclusive proof.
Before reviewing detailed results, the table below outlines the core evidence elements.
How Did the Bathroom Door Lock Fragment Contradict the Suspect’s Story?
The small metal fragment matched the internal latch mechanism of Pennig’s bathroom door. Microscopic tests showed she had no opportunity to remove it herself, and residue analysis indicated the piece came loose only when the door was violently struck from outside. This directly refuted Ecker’s claim of forcing the door from inside the bathroom after a shot was fired.
What Role Did Gunshot Residue and DNA Evidence Play?
Gunshot residue (GSR) detected on Pennig’s clothing and bathroom surfaces established the shot occurred inside the bathroom. Simultaneous DNA swabs on the lock fragment detected skin cells from Pennig and a secondary contributor unrelated to Ecker’s gloves. This combination confirmed a struggle at the threshold rather than a unilateral forced-entry from within.
How Did Hand Placement and Blood Spatter Analysis Contribute?
Blood-spatter patterns on the bathroom wall formed a reverse-scatter pattern indicating the shooter’s hand was near the barrel at the moment of discharge. The spatter angle—and absence of corresponding marks on Ecker’s palms—pointed to another shooter’s positioning and ruled out Ecker’s hands as the trigger source.
What Advances in Forensic Science Were Utilized?
Modern techniques such as high-resolution 3D spatter mapping, next-generation DNA sequencing for trace cells, and metallurgical imaging of lock fragments allowed investigators to reconstruct the precise mechanics of the shooting. These advanced methods offered evidentiary clarity that older techniques could not provide, ensuring definitive alignment of physical facts with eyewitness accounts.
Forensic Science in Criminal Justice
Advances in forensic techniques, such as DNA sequencing and blood spatter analysis, have revolutionized criminal investigations. These methods provide more precise and data-driven results, increasing conviction rates and deterring potential offenders.

What Were the Key Police Interview Findings?
Investigators conducted multiple interviews with Matthew Ecker and neighbors, uncovering:
- Inconsistent timelines regarding the noise and entry sequence.
- A lack of glove or tool residue on Ecker’s clothing despite his forced-entry claim.
- Corroborating witness statements placing Ecker outside Pennig’s apartment prior to the gunshot.
These discrepancies, paired with forensic evidence, undermined Ecker’s credibility and strengthened the case for homicide.
How Did the Investigation Address the Question: Suicide vs. Homicide?
Initial uncertainty included the possibility of suicide, given Pennig’s solitary presence. However, forensic indicators—such as the lock fragment force direction, GSR distribution, and absence of a suicide note—shifted focus firmly to homicide. Detectives systematically ruled out self-inflicted scenarios through comparative analysis of wound trajectory and powder residue.
What Challenges Did Law Enforcement Face?
Investigators navigated obstacles including delayed neighbor statements, initial misclassification of the scene as unsecured, and Ecker’s narrative control of the crime-scene environment. Overcoming these challenges required re-interviews, re-creation of the bathroom layout, and expanded forensic tests to confirm early hypotheses and rectify initial oversights.
