MEGADETH's DAVE MUSTAINE Holds Press Conference To Ask For Help In Search For Missing Mother-In-Law (Video)

MEGADETH mainman Dave Mustaine and his wife Pam held a press conference yesterday (Friday, October 10) at the Sheriff’s Department headquarters in San Diego to ask the public for help in finding his mother-in-law, who is suffering from Alzheimer's disease and has been missing for a week.

75-year-old Sally Estabrook was last seen at a campground near Julian, California on October 4. Her husband noticed she was gone when he returned from a shower and couldn't find her.

Said Dave Mustaine: "Sally Estabrook went missing Saturday at 4 p.m. up at the Pinezanita Campground up in Julian. She has Alzheimer's, severe, [and] she's not communicative. And we're just asking everybody right now, because of the search and how extensively that it's gone, we're looking outside of the camp area now. And we're just asking everybody that may have been up there to take a look in your sheds, in your garages, any of the thick brush around your house. A lot of times, people that wander that have Alzheimer's are found very close to their home. They just take shelter underneath bushes and stuff. So we're asking that you look there. Also, anybody that's working in the medical field, in the hospitals and shelters, any of the senior citizens, adult homes, stuff like that, look at your patients. Maybe there's somebody there that's not supposed to be there. We need your help. For any of you that are watching this right now, we're just asking that if you see Sally — we call her nana — she's probably not gonna answer to you, just call 911 and then we'll go from there."

Added Pam Mustaine: "There's been some sightings in a couple of cities off the mountain, and I'm just wondering, even the fast-food restaurants, if she's with homeless people, travelling around, I don't know that they would know the situation right now, but that they'd be around the fast-food restaurants or taking shelter in places where they can get food. Just looking more into those areas. And again, she wouldn't know how to put two words together. And she may look like a homeless person at this point. But just keeping an eye out maybe in those areas also or even the freeway ramps or however she could be surviving right now on her own."

Search-and-rescue teams from four counties and the U.S. Border Patrol and more than 300 volunteers have taken part in the search for Sally Estabrook.

Estabrook is 5 feet 4 inches tall, about 145 pounds with shoulder-length, blond hair. She was last seen wearing a teal top and white, Capri pants.

Because Estabrook suffers from Alzheimer's, she isn't very communicative, but might respond to her name.

Anyone who sees Estabrook should call 911 or the sheriff's department at (858) 565-5200.

Mustaine revealed last year that a lot of the songwriting process for MEGADETH's 2013 album, "Super Collider", was affected by the fact that he had just found out his mother-in-law had Alzheimer's disease. He told Loudwire: "Until it happens to you, you really have no idea. And I think that when I saw how upset our family became and yet how we are able to provide the resources for her, it made me think about all the families going through this that don't have the resources to take care of a loved one. It also made me really appreciate our fans, because without them, I would not be able to take care of things the way I am. It really brings it all home. And then beyond that, I just did what any good artist does. I put my emotions into my music. That's the pain you hear in the music. It's real. People can say, 'We don’t want to hear this kind of shit,' but to me, this shit is important."

According to Mustaine, the "Super Collider" track "Forget To Remember" was written specifically about some experiences with memory and forgetting that have come very close to home.

"The sad thing about Alzheimer's disease is it's like watching an ice sculpture of somebody you love melt in front of your eyes; it's really, really painful," he told the "Shockwaves" podcast. "So the song has a double entendre where there's a guy and he talks to a girl in the song and it's kind of like the movie 'The Notebook' where the character in the movie, the female, comes in and out of Alzheimer's and she is present and she is back in La La Land again. So you don't really know in this song if it's a girl that is intentionally trying to forget a relationship with a guy or if it's somebody who has Alzheimer's disease, which, really, is what it's about. I worded it so that it could be either way."
