The Chula Vista Police Department served another search warrant at the home of May "Maya" Millete, a mother who's been missing for four months to the day.
SkyRanger 7 flew overhead Friday as officers went in and out of the home on Paseo Los Gatos where Maya Millete was reportedly last seen on Jan. 7. Police have never named her husband as a suspect, and say he is no longer cooperating with their investigation.
It's the second time police have searched the home, according to CVPD. Police were there looking for "signs of death," according to Billy Little Jr. with the Cold Case Foundation.
Officers were seen loading things into the back of a van parked in the driveway, while others led K9's around the property. What appeared to be rifles and boxes typically used to store ammunition were loaded into the van. Meanwhile, 60 to 70 supporters of Maya's family surrounded the property as police worked.
CVPD arrived at the home at around 4:30 p.m. and were still on the property after 11 p.m.
Maya's sister Maricris Drouaillet and brother-in-law Richard Drouaillet raced down from Riverside after friends told them an arrest warrant was being served. They found out while on their way that it was just a search warrant.
"Its been a nightmare. No family should go through this," Maricris Drouaillet said. "Every night we are crying, praying we could see my sister soon. In the morning, we are crying. We don't have any clue where she is. It is heartbreaking."
Chula Vista Police later told NBC 7 they are not commenting on the results of the search and that the status of the investigation has not changed. CVPD is expected to provide an update, as part of their bi-weekly releases on May 19.
A search mission was held on Saturday near Pepper Park in National City. More than 30 people canvased the area on foot and by canoe. Chula Vista and National City police were called to the scene to recover an item. It's unclear if it has any significance to Maya's disappearance, but searchers say they don't take any chances.
CVPD has been releasing bi-weekly updates on the case, including information about interviews and search warrants. On May 4, CVPD said they had conducted 23 search warrants involving "residences, vehicles, cellular and electronic devices, call detail records, financial records, social media and cloud data." Investigators have also conducted more than 50 interviews and followed up on more than 50 tips.
The family claims the department hasn't been completely transparent with them, and staged a rally at department headquarters on May 4 criticizing the investigation.
"[They haven't told us where they've searched] that's why we say it's a one-way communication with the Police department. We don't want to step on each other's feet. If you search In one area, please let us know. That way we don't have to waste our time," Maya Millete's brother-in-law Richard Drouaillet told NBC 7.
Investigators described Maya as 5 feet, 2 inches tall and 105 pounds, with brown hair, brown eyes and freckles. Her family said she has a tattoo on her wrist.
Chula Vista police said last month that the San Diego District Attorney’s Office, the FBI and the Naval Criminal Investigative Service (NCIS) were all working on the investigation.
Searches for Maya have been conducted by family, loved ones and even strangers who just want her found. The efforts have even expanded across county lines in the hopes that something will turn up to provide a clue to her whereabouts.
Maya's family said they created a website with information on how to support their efforts and any future searches, as well as blog updates from her loved ones.
The criminal investigation into Millete's disappearance is ongoing. Police are urging anyone with information on her whereabouts to contact detectives at (619) 691-5139. Tips can be called in anonymously to Crime Stoppers at (888) 580-8477.
