 (CNN) When the cops showed up to a subdivision Wednesday night in Oldsmar, Florida, it wasn't to break up a loud party or for any sort of bacchanalian revelry typical of New Year's Eve. Christian Gomez 
 
 Responding deputies found the decapitated body of 48-year-old Maria Suarez Cassagne alongside garbage cans outside of the Tampa-area home, according to the Pinellas County Sheriff's Office. No, Mario Gomez called 911 to report something far more sinister and ghastly: His brother had just cut off their mother's head with an ax. Investigators said Christian Gomez attacked his mother with the ax in the garage, then put her head in a trash can in a small side yard. Christian Gomez, 23, flashed a toothy grin while being booked for first-degree murder Wednesday after his brother called 911 to report the gruesome scene at the house near Tampa around 7:20 p.m., authorities said. "You could definitely see that he was traumatized, and he was just bending down and crying and talking to the police," Rivera said. Gomez told the authorities that his younger brother, Christian Gomez, had fled the scene, but he didn't make it too far. Gomez had already fled the scene but was found a few blocks away when a 911 call came in about a "suspicious person riding a bicycle in the area," said the sheriff's office. After a brief foot chase he was arrested and allegedly admitted to the crime during an interview with detectives, revealing that he had plotted out his mother's death for two days, Sheriff Bob Gualtieri told WFTS. Gomez had a history of mental illness and had been planning to kill her for two days, the sheriff said.
– A 23-year-old man beheaded his mother with an axe on New Year's Eve and explained to investigators that he was fed up with her nagging him to put some boxes away, authorities in Oldsmar, Fla., say. Cops were called to the Tampa-area home after the older brother of Christian Gomez discovered his mother's decapitated body near garbage cans outside, CNN reports. The younger Gomez had already fled the scene but he was captured a few blocks away after police received a call about a suspicious person riding a bicycle. The local sheriff says Gomez, who has a history of mental illness, confessed to the killing and said he had planned it for two days. "In a very calm, cool way he explained what he did, why he did it, what happened, and by talking to him you wouldn't know he had any mental illness, he had any trouble at all. And you know that's very scary," the sheriff tells WFTS. Gomez, who has been charged with first-degree murder, was arrested in 2009 for resisting an officer without violence and disorderly conduct and in March 2014 for loitering and prowling, reports the New York Daily News.
