One day after the body of a black female was found near the site of a crash that killed at least five members of the Hart family, the Mendocino County Sheriff's Office is gearing up for another search and rescue operation.

Three children -- Hannah Hart, 16, Sierra Hart, 12, and Devonte Hart, also 15 -- are still missing after the crash on the Northern California coast that officials believe could have been intentional. Parents Sarah and Jennifer Hart, both age 38, were killed, and children Markis, 19, Jeremiah, 14, and Abigail, 14, also died.

No determination of the age or identity of the body has been made, and the Mendocino County Sheriff's Office said DNA analysis could take several weeks. An autopsy on the body is scheduled for Tuesday.

Officials are hoping to find more evidence in the water after a storm caused currents to change and potentially shift crash debris that may have been lodged on the ocean floor.

"We're going to try to get a search and rescue crew, even if it's limited," Mendocino County Sheriff Lt. Shannon Barney said in a phone interview Sunday with The Oregonian/OregonLive.

Stormy weather has halted the intense search for the missing family members and belongings, but Barney said it will likely resume Monday.

Barney said the search will be staffed by all volunteers, so he couldn't yet say how many people will be involved.

"You get who you get," he said.

"It's usually easier on the weekends," he added, when more people are available to volunteer.

Barney is also hoping to get a helicopter to support the effort.

Investigators have been trying to determine what sent the Hart family over the California cliff since their vehicle was spotted by a passer-by March 26. Police said they believe Jennifer Hart was driving the SUV when it came to a complete stop then accelerated off the edge of a dirt pullout off of Highway 1.

The Harts, who lived in West Linn but had recently moved to Woodland, Washington, left their home shortly after a visit from authorities regarding reported child abuse and neglect concerns. The mothers had been the source of previous abuse reports since adopting the first of their children in 2006.
