The police timeline runs through a 911 call, a surveillance video, a disputed elevator statement and evidence recovered from a balcony.
MIAMI BEACH, Fla. — A roughly 10-minute timeline at a Miami Beach condo tower now anchors the murder case against Corey Hutterli in the death of Justin Zelin, after investigators compared emergency audio with video and evidence from the apartment, police said.
The timeline starts with Zelin’s call for help, moves through sounds of a struggle, and ends with surveillance footage showing him hitting the pavement outside the Akoya Condominium. Police say the evidence from those minutes led investigators to Hutterli, 37, of Parkland, who was arrested April 8 on charges of second-degree murder and burglary with assault or battery. Hutterli’s defense has disputed whether the timeline proves he caused the fall.
The first point in the sequence was the emergency call from Zelin’s 25th-floor apartment at about 10:20 a.m. Feb. 15. Police said Zelin, 35, reported a disturbance and told Hutterli to leave. He also told someone he called Sasha to get away from him, according to the complaint described in public reports. Investigators said Sasha was a name used by Hutterli. The call continued after Zelin stopped speaking. Dispatchers then heard sounds police described as a violent struggle. That open line became more than a request for help because it gave investigators a running record of the confrontation before cameras recorded the fatal fall. It also gave police a time stamp they could compare with elevator activity, hallway movement and the arrival of first responders.
The second point was outside the tower. Security video showed Zelin’s body striking the pavement at about 10:30 a.m., police said. Officers arrived soon after and encountered Hutterli as he left or moved near the apartment area. Police said he appeared distressed and agitated. He was in socks and had no shoes. That detail later matched evidence found in the unit because investigators said Hutterli’s sandals were on the balcony. In the first minutes after officers arrived, the investigation depended on matching what Hutterli said with what the call, cameras and scene appeared to show. Police later treated the missing shoes as a small but important clue linking his rushed exit to the balcony evidence and the disorder officers described inside the unit.
The third point was Hutterli’s explanation to police. Investigators said he told officers that Zelin had attacked him and that he had been trying to calm Zelin down. When asked where Zelin was, Hutterli said he did not know, according to police. He then said Zelin had gone to the elevator. Investigators said that statement did not fit the camera timeline because Zelin had already fallen outside the building. Police also said Hutterli asked whether Zelin had jumped. The elevator statement became one of the case’s most visible details because it placed Hutterli’s words against the building’s surveillance record. It also gave prosecutors a statement they can present as inconsistent with the physical timeline described by investigators and with Zelin’s body already outside the tower.
The fourth point was the apartment itself. Officers found the balcony doors open and the unit in disorder, according to police. Blood was found on the balcony railing. Tufts of beard hair were found in several areas of the apartment, and later testing linked the hair to Hutterli. Officers also recorded injuries on Hutterli, including cuts on his hands, scratches and redness on his arms, and areas where beard hair appeared to be missing. Those observations gave detectives evidence of a fight, but public reports do not include a complete frame-by-frame account of how the struggle moved through the apartment. The findings instead mark points of contact, injury and disorder that prosecutors are expected to use as circumstantial proof of a violent confrontation.
The fifth point came later through forensic testing. Police said Hutterli’s DNA matched blood found on the balcony railing. They also said blood on Hutterli’s clothing was linked to both Hutterli and Zelin. Investigators said a search warrant later produced Hutterli’s backpack from inside the apartment. Police said the bag contained additional beard hair and alleged that the evidence suggested an attempt to recover or conceal items from the scene. Investigators also reported finding ketamine in the backpack. Police have not publicly said that the drug finding explains a motive, and the public record does not show what role, if any, it will play in court. The forensic material is likely to be reviewed alongside photographs, lab reports and testimony from officers who collected and preserved the evidence.
The sixth point was the charging decision. Investigators moved from a fatal fall inquiry to a homicide case after collecting the 911 recording, reviewing surveillance footage and receiving forensic results. A second-degree murder charge does not require prosecutors to prove that Hutterli planned Zelin’s death in advance. It does require proof of an unlawful killing carried out with a depraved mind and without lawful justification. The burglary with assault or battery charge adds another element involving Hutterli’s presence in the apartment. Those charges show that prosecutors are not treating the fall as an isolated accident but as the alleged result of a criminal confrontation. Prosecutors still must prove each charge with admissible evidence, and the defense can challenge the state’s interpretation of the timeline.
The timeline also shows what remains unknown. Police have not publicly announced a motive. Reports have not fully explained the relationship between Zelin and Hutterli or what led Hutterli to be inside Zelin’s apartment that morning. The public case summary does not state every word on the 911 recording, every camera angle reviewed or every item collected from the unit. It also does not show video from inside the apartment. Those limits matter because the most contested part of the case is the moment between the struggle heard on the call and the fall recorded outside. The missing interior view gives both sides room to argue about whether the available evidence proves the final act or only the surrounding conflict.
Hutterli’s defense has focused on that missing interior view. His attorney said at an early court appearance that there was no eyewitness to the act that caused Zelin’s death, no confession and no direct evidence proving who caused the fatal injuries. The defense argument does not change the police timeline, but it challenges what can be inferred from it. Prosecutors are expected to argue that the separate points line up: Zelin called for help, a struggle was heard, he fell, Hutterli left without shoes and physical evidence tied him to the balcony and Zelin. The defense can answer that a chain of events is not the same as proof of a criminal act unless the state closes the final gap.
Beyond the sequence of minutes and evidence, Zelin’s friends have described a wider loss. Amit Jolly, a friend, said Zelin was “a big presence” in the Jewish community and the biotech community. Local reports identified Zelin as a Harvard graduate and biotech professional. Jolly said the final moments should not define him, even as those moments shape the criminal case. His comments added a personal frame to a timeline built from dispatch audio, cameras, blood evidence and police reports. Jolly said Zelin should be remembered for his life and work, not only for the facts recited in court. That personal account gives the public record a second timeline, one that reaches back before the emergency call and the fatal fall.
The case remains focused on a narrow gap in time between the open 911 line and the fall captured outside the tower. Investigators say the surrounding evidence points to Hutterli, while the defense is expected to press the question no camera has publicly answered.
