A man suspected of fatally shooting five people and critically wounding a 13-year-old girl in shootings at two nearby apartments in North Las Vegas, Nev., killed himself on Tuesday morning after he was cornered by the police following a manhunt, the authorities said.

The man, Eric Adams, 47, died by suicide after ignoring commands by officers with the North Las Vegas Police Department to drop a firearm he had been holding, the police said in a statement on Tuesday.

In a news release, the police had previously warned area residents that Mr. Adams was armed and “considered to be extremely dangerous.”

It is unclear what the relationship was between Mr. Adams and the victims, who were discovered late Monday night. Officers who responded to reports of a shooting at an apartment on Casa Norte Drive found two women, one in her early 40s and the other in her late 50s, with apparent gunshot wounds. The women were later pronounced dead, the police said. A 13-year-old girl who had also apparently been shot was taken to a hospital in critical condition, the police said.

The police also found three other people who had apparently been fatally shot at a nearby apartment: two women in their mid-20s, and a man in his early 20s. All three were pronounced dead at the scene, the police said. None of the victims have been publicly identified.

The police said the shootings were considered an “isolated incident,” and that no further details were available.

The Las Vegas Review-Journal reported that two coroner vans and several police cars were parked in front of an apartment complex on Casa Norte Drive on Tuesday, and that the police had closed off a section of it with crime scene tape.
