HENDERSON, Nev. (KLAS) — Henderson Police are investigating the deaths of two children at a home near Galleria Drive and U.S. 95. Units responded to a medical emergency in the 700 block of Calamus Palm Place Monday around 6:33 p.m.

The deaths are being investigated as homicides.

Paramedics observed the children were “beyond assistance” and declared them dead at the scene. Police said in a news release Tuesday they were a 1-year-old girl and a 4-year-old boy.

According to HPD, the incident “appears to be suspicious in nature.”

Residents tell 8 News Now they didn’t hear anything but saw an influx of police cars enter the neighborhood all at once. They recount a man was seen on the ground, undetained, kneeling with his head down. Police have not said if anyone was arrested.

The Clark County Coroner will release the children’s names after next of kin is notified.

Neighbors are shocked and wondering what happened. The area is described as quiet and kid-friendly.

Ayanna McKeever has lived there for six years. She says she never saw children at the house but would see a man taking out the trash and checking mail. She tells us Monday night, she saw police, ambulances and fire trucks on the street.

“Yesterday, my father-in-law comes running down the stairs because his brother is the chief of Henderson Fire Department,” McKeever recalled, “and he was like, ‘What’s you guys’ address because we just got a call of a 2 and 4-year-old drowning.'”

HPD has not revealed if this investigation involves the drowning of the kids.

McKeever recalls seeing a man, who she believes to be the father, sitting on the curb for two to three hours, detached from the situation. She says he was later placed in a police car but did not see handcuffs on him.

“Didn’t shed a tear,” McKeever recounted. “I know people say shock hits you at different times, but if my children just died, even if it was accidental, if I accidentally did it, there will be emotion … Someone was either careless enough that something did happen, or they were disgusting enough to do something.”

She also told us about the children’s grandmother:

“She ran out of the car to go to the house, and the police stopped her, and she was like, ‘My grandbabies, where are my grandbabies?'”

McKeever hopes there is justice for them.

“The police officer’s comment was, ‘I’ll never be the same after tonight,'” she shared.

The investigation is ongoing.

Neighbors tell 8 News Now they are planning a candlelight vigil for the children Wednesday at 6:30 p.m.

The deaths are the ninth and 10th homicides investigated by Henderson Police in 2021.
