A man who killed a toddler in his home died in hospital, a hospital spokesman said.
Johnathan J. Lewis, 23, of New London died of an apparent suicide, the New London Health Department said in a statement on Sunday.
Lewis was arrested by authorities on Sunday and taken to the hospital where he was pronounced dead, the department said.
Lewis has been charged with first-degree murder, attempted first-level murder, assault with a deadly weapon, aggravated battery on a person 65 or older and reckless endangerment.
The incident comes amid a nationwide shortage of pediatricians.
Last week, the American Academy of Pediatrics said that a shortage of 4,500 pediatricians was threatening the ability of the nation’s pediatric health care system to care for the nations 1.2 million children.
The shortage is largely blamed on the growing use of new technology, including electronic medical records and telemedicine.
