Police say the suspect confessed after officers were called to an apartment for a medical assist at Grace House on Abbott Terrace.
WATERBURY, Conn. — A 48-year-old Waterbury man is accused of fatally stabbing his 80-year-old mother inside her apartment at an elderly housing complex, and a judge set his bond at $2.5 million a day after officers answered what began as a medical assist call.
Police identified the suspect as Noel Sepulveda and the victim as Anacelia Sepulveda, his mother. The case drew immediate attention in Waterbury because it unfolded inside Grace House, a senior housing property on Abbott Terrace, and because prosecutors say the defendant confessed, pointed officers to the weapon and described what happened before his arrest.
According to police, officers were dispatched to the apartment around 12:42 p.m. Thursday after a call for medical help. When they entered, they found Noel Sepulveda on the floor of the apartment and Anacelia Sepulveda unresponsive in bed with multiple stab wounds. She later was pronounced dead. Police said the son appeared to be under the influence of drugs when officers arrived. He was taken first to a local hospital, then charged in the case. By Friday morning, he was in Waterbury Superior Court facing a murder count along with charges of possession of narcotics and use of drug paraphernalia. The shift from a welfare-type response to a homicide arrest happened in less than a day, giving the case a fast and public start in court.
At the arraignment, Supervisory Assistant State’s Attorney Don E. Therkildsen Jr. said Sepulveda gave police a full confession and told investigators that he also tried to kill himself. Therkildsen said the defendant directed officers to the murder weapon, which police later recovered through a search warrant, and also told them where to find bloody clothing. Those details, if backed by physical evidence and later testimony, are likely to become central parts of the prosecution’s case. Still, some key questions remain unanswered in public. Police have not publicly described a clear motive, have not released a detailed timeline of the moments before the stabbing, and have not said whether anyone else was inside the apartment when the attack happened. Authorities also have not publicly explained what type of narcotics they believe were involved.
The setting has added another layer to the case. Grace House is an elderly housing complex on Abbott Terrace, where at least one member of each household must be 62 or older. Before police publicly identified the victim and suspect, officers said detectives were investigating a death at the property and released few details. That early silence reflected the usual pattern in homicide cases, where investigators work to identify victims, notify family and secure evidence before announcing arrests. By Friday, a clearer picture had emerged: prosecutors said the victim was killed in her own bedroom, while the defendant was found elsewhere in the apartment. The fact that the victim was an 80-year-old woman found dead in bed is likely to shape how the case is viewed in court and in the community, even before any trial testimony begins.
Defense attorney Emily Claffey told the court there were mitigating factors in the police report and said the homicide may have been driven by what she described as a very severe, quick-onset mental health crisis. Judge Frank Iannotti did not reduce bond and said mental health questions would become trial issues. A bail commissioner’s report, discussed in court, said Sepulveda has prior convictions dating from 1996 to 2000, including violation of probation, possession of narcotics and failure to appear. Those older convictions are separate from the current allegations, but they helped shape the bond discussion as the judge weighed the seriousness of the charge. The murder case will next move through the usual pretrial steps, including evidence review, motions and possible competency or mental health questions if the defense raises them more fully.
The public account of the case widened after relatives began to speak. Rafael Sepulveda, who identified himself in television coverage as Noel’s brother and Anacelia’s son, described years of substance abuse in the family and spoke in emotional terms about the shock of the killing. “I am mad,” Rafael Sepulveda said, before adding that he could not bring himself to say he hated his brother after what the family had endured over the years. His remarks did not change the court record, but they added a human voice to a case that otherwise has been defined by police statements and arraignment details. They also pointed to the strain that addiction and mental health concerns can place on a family long before a criminal case reaches a courtroom.
As of Sunday, Noel Sepulveda remained charged with murder and drug offenses in the death of Anacelia Sepulveda. The next public milestone is expected to come in court as prosecutors and defense lawyers return for the early procedural stages of the case.
