CHULA VISTA, Calif. – Chula Vista police on Friday afternoon served another search warrant at the family home of Maya Millete, who has been missing for four months.

Police arrived about 4:30 p.m. to the home in the 2400 block of Paseo Los Gatos, Chula Vista police Lt. Frank Giaime told FOX 5. No arrests are being made and no further details were provided.

Millete, whose 40th birthday was Saturday, last was seen at about 5 p.m. on Jan. 7 near her home in Chula Vista. Family believed that it was possible Millete may have gone hiking in the canyon behind the property. Her car remained in the driveway and her phone was reported as being off.

Officers were notified Jan. 10 of Millete’s disappearance, at which time police searched the home and vehicles.

Police served a search warrant at the family’s home Jan. 23 “to obtain any evidence and clues to her current whereabouts.” Another search warrant was served at the home of another Millete relative on April 1. It is unclear if investigators found anything helpful during the searches.

The search continues for Maya Millete, a missing Chula Vista wife and mom of three.

Numerous rallies and searches have been held in the South Bay and elsewhere, but no signs of her have turned up in the weeks and months she’s been gone. Much of the search effort has been led by Millete’s sister and brother-in-law, Maricris and Richard Drouaillet.

“We’re hoping for, you know, closure,” Maricris Drouaillet told FOX 5 on Friday. “It’s been four months and it’s been too long. We’re trying to be patient, but the frustrations with the family and just the waiting, it’s a long time. “It’s heartbreaking.”

Millete’s husband, Larry, has not attended any of the recent public searches or events. As of Feb. 3, police said he had retained an attorney and was no longer answering police questions.

The couple’s three children were home when police arrived. FOX 5 reached out to Larry and his lawyer for comment on the new search warrant, but had not heard back as of late Friday.

Millete’s sister and brother-in-law have been careful not accuse Larry in Maya’s disappearance, but they say it speaks volumes that he hasn’t communicated with them or told them he’s innocent.

“I wish he could just come forward and tell us he has nothing to do with my sister’s disappearance,” Maricris said. “I’m still praying. I’m hoping he doesn’t have anything to do with her disappearance.”

Both of the family’s cars were seen in the garage of the home and a white police evidence van was parked in the driveway for much of the evening. At about 10:15 p.m., the van was pulled to the side of the driveway and a black vehicle was pulled out of the garage and parked next to the van.

Around 11 p.m., investigators were observed hauling boxes out of the house and loading them into the evidence van in the driveway before it pulled away.

“It’s traumatizing to the kids, I’m guessing, to see all this activity,” Richard Drouaillet said. “They don’t know what’s going on.”

In a recent update, police said they’ve written 23 total warrants and conducted nearly 60 interviews in the search for Millete. More than 55 tips also have been reviewed, including recent ones that said Millete possibly had been spotted in New Mexico and Wisconsin.

Police also announced this week that Josephine Wentzel, an advocate from the Cold Case Foundation, was assigned to work as a liaison between Millete’s family and law enforcement.

“I recognize the pain and concern May’s disappearance has brought to her family, friends and the community and I am grateful for the outpouring of support May’s family has received during this difficult time,” Chula Vista police Chief Roxana Kennedy said in a statement Tuesday.

“Our investigators along with the multi-agency working group are dedicated to finding May or bringing Justice to May’s family.”
