A 10-day-old baby boy was killed on the weekend when a gunman entered his home and shot him to death in Kansas, the state’s police chief said.

The baby’s death came hours after a police officer was wounded in a shooting in the city of Lawrence, about 75 miles (120 kilometers) south of Kansas City, authorities said.

No other details were immediately released.

Authorities have identified the boy as Eric, but family members did not immediately respond to messages seeking comment.

Police had initially reported a manhunt for the suspect, but said he fled after officers confronted him and the boy was found unresponsive at a home.

Authorities later released a surveillance video of the suspect and the infant.

The suspect, identified as a white man in his 30s, is seen walking away from the home before opening fire, striking the baby.

A manhunt was launched after the shooting and a large police presence surrounded the home, a rural community near a highway and railroad.

The shooting happened just hours after two Kansas residents were fatally shot in their homes, and more than 50 people were wounded in shootings across the U.S. and Canada on Saturday.

The latest shooting came as Kansas and other states grappled with a wave of gun violence that has been fueled by the availability of the powerful assault-style rifle.

On Thursday, a gunman killed six people and wounded at least 21 in a rampage in rural Louisiana.

On Saturday, a Kansas man was charged with a homicide and assault after he opened fire at a gas station and a convenience store in suburban St. Louis, killing two people and wounding a third.
