A waitress and customer escaped physical injury in the August holdup before a separate September encounter ended with a 23-year-old man dead.
KANSAS CITY, Mo. — A late-night armed robbery that sent a customer scrambling behind a Waffle House counter ended with no one physically hurt, but the teenager responsible was arrested weeks later in a separate case that ended in a man’s death and ultimately produced two lengthy Missouri prison sentences.
The two cases against Undrellius K. Fleck, now 18, unfolded in different Kansas City counties and reached different courts, but together they account for the prison terms he is now serving. Fleck received 30 years for first-degree robbery in Clay County over the Aug. 21, 2025, Waffle House incident. He had already been sentenced to 23 years in Jackson County after pleading guilty in a case involving the Sept. 6 shooting death of 23-year-old Kenneth Hutt. A judge ordered the newer 30-year sentence to run concurrently with the earlier term, meaning both sentences operate at the same time rather than being stacked one after the other.
The Waffle House encounter began with an effort to escape. Court records cited by KCTV and The Kansas City Star say a man was leaving the restaurant at 4404 N. Antioch Road shortly after 10:20 p.m. when Fleck came toward him with a gun. The man ran back through the restaurant’s doors, crossed the customer area and jumped over the counter. He positioned himself behind a waitress. Fleck followed rather than ending the pursuit outside. Investigators said he entered with a black handgun fitted with a light, pointed it toward the customer and demanded the man’s cellphone. The confrontation was recorded on surveillance video, according to authorities.
The waitress became a second person directly exposed to the threat. According to court records quoted by KCTV, Fleck told the customer to give him the phone and to hurry, then threatened to shoot while the weapon was pointed in the waitress’s direction. She later told investigators that she could see the firearm’s light across her chest and believed she might die. The customer surrendered his phone, after which Fleck left. Despite the close-range threat, neither the customer nor the waitress was physically injured. The waitress later identified Fleck in a photo lineup, authorities said, giving investigators eyewitness evidence in addition to the restaurant’s surveillance recording.
Another detail had been recorded by police even before the robbery happened. The day before the Waffle House incident, officers had stopped a gray Nissan Altima associated with the customer’s ex-girlfriend, according to KCTV’s account of the court records. During that traffic stop, the woman was on the phone. Investigators said she told officers she was speaking with her boyfriend, Fleck. The record gave police a documented connection as they built the robbery case. Publicly available accounts do not explain every step investigators took between the restaurant robbery and the later filing of the Clay County charge, so the significance of any individual lead should not be overstated.
Before the Waffle House case reached its final sentencing, however, a separate and far more serious case began in Jackson County. On Sept. 6, only 16 days after the robbery, officers were sent to a south Kansas City convenience store shortly before 11:30 p.m. A police detective’s probable cause statement says officers found a man inside suffering from multiple gunshot wounds. Kansas City Fire Department personnel confirmed his death at the scene. The man was later publicly identified as Hutt, 23. Investigators recovered surveillance video and numerous shell casings, allowing detectives to reconstruct the moments before the shooting from the store’s cameras.
The surveillance account did not begin with the shooting itself. Investigators said a gray Nissan arrived at a gas pump several minutes earlier. Fleck, who was still a juvenile at the time, and another male went into the store and selected items. The probable cause statement says one of them unsuccessfully tried to pay electronically before Fleck paid cash, and the two returned outside. Hutt then arrived in another vehicle and entered the store. Detectives said video appeared to show a pistol tucked beneath Hutt’s left arm. Fleck and the other male went back inside with their hoods raised, according to the statement, and appeared to focus their attention on Hutt.
What followed became the basis for murder and robbery charges. The detective wrote that the second male produced a small AK-style pistol and handed it to Fleck before approaching Hutt from behind and trying to take Hutt’s firearm. Investigators said Hutt tried to keep control of his gun. At that point, the statement says, Fleck raised a Glock-style handgun with a drum magazine and fired toward Hutt. The gunfire appeared on video to be fully automatic, police said. After Hutt fell and dropped his firearm, investigators alleged that Fleck picked it up. Fleck and the other male then ran back to the Nissan and left the parking lot.
The description of the handgun drew special attention in the charging records because detectives believed they could see a component commonly called a switch on the back of the pistol. Such a device can allow a semiautomatic firearm to fire automatically. The probable cause statement used the apparent modification and the appearance of the gunfire on surveillance as part of the factual basis for the case. Prosecutors eventually charged Fleck with second-degree murder, first-degree robbery and two counts of armed criminal action. Those were accusations when filed in December 2025. Fleck later pleaded guilty in the case, while a second defendant, Jordan A. Vasquez, continues to face his own charges.
The route to Fleck’s arrest also came through the Nissan identified by investigators. On Sept. 9, three days after Hutt was killed, officers operating in what the probable cause statement described as a covert capacity began following the gray vehicle. A car check took place near Emanuel Cleaver II Boulevard and Forest Avenue. Police said Fleck got out and ran before officers caught him. He was booked and taken to juvenile detention. Because of his age at the time of the crimes, adult prosecution required an additional court step. Jackson County records say Fleck was certified through the juvenile court as an adult on Dec. 18. Prosecutors announced the adult criminal charges the following day.
Fleck resolved the Jackson County case first. The prosecutor’s office says he pleaded guilty in February 2026 and was sentenced May 28 to 23 years in prison. That sentence came before the Clay County Waffle House prosecution reached its own final disposition. In July, Fleck pleaded guilty to first-degree robbery in Clay County and received a 30-year term from Judge Shane T. Alexander, according to The Kansas City Star. The newspaper reported that a count of armed criminal action in the Clay County case was dismissed as part of the plea agreement. Prosecutors had also noted that Fleck, originally charged as a juvenile in the robbery matter, was certified to stand trial as an adult.
The difference between the two incidents is stark in outcome but not in the seriousness with which authorities treated the threats. At the Waffle House, the targeted customer handed over a phone and both people facing the weapon survived without physical injury. In the Jackson County store, the encounter described by investigators ended with Hutt dead and his firearm taken. The legal systems in both counties ultimately imposed prison terms after Fleck’s cases moved into adult court. The concurrent sentencing order does not erase either judgment; it governs when the time is served. Fleck remains subject to the longer 30-year Clay County term while the 23-year Jackson County term runs alongside it.
The Jackson County case also remains open as to Vasquez. The prosecutor’s office says Vasquez is scheduled for trial in February 2027. His charges are allegations and must be treated separately from Fleck’s guilty plea. KCTV additionally reported in July that Fleck faced identity theft, burglary and theft charges in Johnson County, Kansas, but no final resolution of those allegations was located in the materials reviewed for this story. As of the latest verified Missouri updates, Fleck has been sentenced in both the Waffle House robbery and Hutt’s killing, while proceedings involving the co-defendant continue.
