A man from Minnesota faces manslaughter charges following the tragic asphyxiation death of his infant son.
Twenty-six-year-old Omni Maxx Morningstar was released on bond after his arrest and booking into the Blue Earth County Jail on the manslaughter charge. As stated by Mankato city authorities, Morningstar was taken into custody on Monday after a probe into the demise of his 10-month-old son, Remington. Details from a criminal complaint obtained by Law&Crime reveal that on October 1, 2025, Morningstar placed his son face down for a nap on a bed and covered him with a 20-pound weighted blanket.
Authorities reported that Morningstar subsequently went to another room, closed the door, and put on headphones to engage in an online chat with friends via Discord.
The complaint notes that emergency personnel, including police and firefighters, arrived at Morningstar’s Mankato apartment at 3:54 p.m. in response to a medical emergency involving the baby, who lived there with his father and mother. When a firefighter inquired about the emergency, Morningstar allegedly replied it was about “a practically dead baby.”
Upon arrival, responders found the infant showing no signs of life; his extremities were cold, yet his body temperature remained high. Sadly, Remington was declared dead at the hospital an hour later, at 4:54 p.m.
Morningstar told officers at the scene that he took the baby’s temperature earlier that day and it was 104.7. According to the complaint, he told officers that his son’s temperature was “only 105, but you know what’s interesting, [he] exhibits the same symptoms as someone was 108.” He said Remington felt like he was “on fire,” and his lips were blue.
Police said Morningstar told them he put Remington down for a nap in the bedroom at 11 a.m., placing him face down with a 20-pound weighted blanket over him, covering his body up to his shoulder blades. He did not check on him again until almost 4 p.m. He told officers that he left the baby’s bedroom door open, but allegedly went into his own bedroom and closed the door. He then allegedly put on a pair of headphones and started chatting with friends on Discord.
According to the complaint, Morningstar said, “I’m thinking in my head like, [five] hours. Huh. I really do wish I would have checked on him. I mean, it only happened twice before. It spiked two times and we fixed him two times.” Morningstar explained to police that Remington was “colicky,” and the weighted blanket helped him.
Police said Morningstar also said that he started using a 12-pound weighted blanket during Remington’s naps four to five months earlier to keep his legs from moving. He stated that Remington was hospitalized about a month prior to his death when he became overheated, his body temperature reaching 104 degrees. Morningstar told police that “he had been cautioned about using a blanket at the hospital.”
Remington’s mother told police more about the previous incident, saying that she walked in to find the baby covered “head to toe” with a king-sized comforter. She was the one who took the baby’s temperature and called 911. Police said Morningstar told her that he “forgot” about the baby because he “was playing video games.”
According to the complaint, Morningstar also admitted to using the blankets to cover Remington’s head and would wear headphones to muffle his baby’s crying.
The medical examiner determined that Remington’s cause of death was probable asphyxia caused by the weighted blanket.
Morningstar was arrested on Monday and bonded out of Blue Earth County Jail on Wednesday. His next court appearance is scheduled for April 16.
