Sections of a park in Phoenix were closed over the weekend after police investigating the discovery of a human skull found earlier this month located more human remains, authorities said Sunday.

Investigators were searching for evidence in a homicide at South Mountain Park and Preserve after detectives located the additional human remains on Saturday, police said.

The search was sparked after a hiker reported finding a human skull at the preserve on Jan. 14.

Signs of trauma appeared on the skull, according to authorities, prompting police to investigate the death as a homicide.
