In a startling incident at an In-N-Out Burger in Colorado, the CEO of a private equity firm, Lucas Kalisher, was sentenced to 30 months of probation after attacking a teenager. The altercation occurred when the teen accidentally splashed water on a woman accompanying Kalisher, prompting him to violently confront the youth. The court has mandated that Kalisher write an apology letter to the victim.

The sentencing, which took place on Tuesday, followed Kalisher’s guilty plea to attempted second-degree assault by strangulation, as reported by the 8th Judicial District Attorney’s Office to Law & Crime. At the time of the incident, Kalisher was the CEO of Summit Source Funding, a firm based in Boulder. In addition to his probation, the court has ordered Kalisher to undergo an anger management evaluation, complete 120 hours of community service, and avoid any contact with the victim. He is also required to pay over $200 in restitution.

The confrontation unfolded in August 2024 at an In-N-Out located at 1450 Fall River Drive in Loveland. According to a police press release, officers responded to reports of an altercation involving a 15-year-old boy. The teen recounted that he and friends were engaged in playful water splashing inside the restaurant when a nearby woman was inadvertently caught in the crossfire. The young man approached her to apologize, but Kalisher reacted by grabbing him, choking him, and forcibly throwing him to the ground.

Following the incident, Kalisher and the woman left the scene, sparking a week-long investigation by police. Authorities reviewed witness testimonies and analyzed cellphone footage uploaded online, which provided various perspectives on the event, as detailed in the police report.

“During this interaction an adult female was accidentally splashed with water,” the release says. “The juvenile male approached her table to apologize when an adult male accompanying the woman suddenly grabbed him, placed both hands around the front and back of his neck, pulled him down to the table and threw him backward onto the floor.”

Kalisher and the woman left the In-N-Out, with cops spending the following week investigating what happened and interviewing witnesses. Cellphone video posted online was also probed and “depicted different views of the incident,” the police press release says.

“Witnesses came forward and were able to identify [Kalisher],” the release explains.

Kalisher was charged about a week later with second-degree assault by strangulation and child abuse after turning himself in. The charges were dropped as part of Kalisher’s plea deal, while he agreed to admit guilt to attempted assault.

The DA’s office told Law&Crime that if Kalisher does not complete and abide by the terms of his plea deal, he will face sentencing for a class 5 felony, as well as one to three years in prison.

Kalisher’s now-deleted LinkedIn page listed him as a CEO of Summit Source Funding at the time of the incident, as well as prior news reports. The status of his employment could not be confirmed Wednesday, as the company did not respond to Law&Crime’s requests for comment.
