Police have interviewed people who last had contact with Carly Scott before she disappeared, including her ex-boyfriend, Capt. John Jakubczak said at a news conference.
Scott was reported missing on Feb. 10 by her mother. The 27-year-old redhead, who is five months pregnant, was last seen at her sister's home in Haiku at 8 p.m. the night before, Jakubczak said.
Family members have said Scott left her sister's house to help her ex-boyfriend, whose car had broken down on Hana Highway.
Last Wednesday, Scott's SUV was found torched. Jakubczak said a private search party found clothing and other items the following day that Scott's family identified as belonging to her. Police have the items and were processing them, he said.
Jakubczak said the investigation continues to be classified as a missing person's case.
"We encourage the community, the public, to call with any information they have no matter how minute or how small they believe it is because we'll follow up on every lead or tip," Jakubczak said, according to an audio recording of the press conference provided by Maui police.
Maui police were also looking for another missing woman, Moreira Monsalve, who was last seen in January. Jakubczak said there's no evidence the cases are connected, though they are similar. Monsalve, 46, was also last seen by her ex-boyfriend.
A team of 50 to 70 volunteers and family members have been searching for Scott since her mother reported her missing.
But Maui Mayor Alan Arakawa urged the public to allow investigators to do their job.
"Even though there's an urgency to try and solve these cases, one has to be very, very patient, those in our community have to be patient, to allow that process to evolve," he said. "Otherwise, we'll jeopardize the potential of being able to use whatever evidence is being found."
Scott's mother, Kimberlyn Scott, a href="http://ow.ly/tKIqR0">told the Maui News that the family would be "taking a breather" and wouldn't be actively searching Tuesday.
The team has been conducting daily searches from Haiku to Hana, by foot, on motorcycles and on all-terrain vehicles. They are armed with maps of the island and donated support including search dogs and a drone that took pictures and video of unreachable cliffs and ravines.
Carly Scott, who goes by the nickname Charli, was born in Woodland, Calif., grew up in Sacramento and moved to Maui about 10 years ago.
Her father, Robert Scott, flew in from Seattle last week. More than a dozen relatives have flown in from the mainland.
