McStay family murder suspect Charles Ray Merritt will appear in San Bernardino Superior Court on Monday to hash out issues regarding evidence he has requested from the prosecutor so he can prepare his defense.

Merritt, 57, of Homeland is defending himself in the potential death penalty case.

He filed a 10-page motion with the court on March 6 requesting that prosecutor Sean Daugherty turn over myriad items of evidence including the names, addresses and telephone numbers of all witnesses and the statements they made to police, the original notes taken by investigators in San Bernardino and San Diego counties, all photos, videos and other media related to the case, and all reports and records pertaining to any physical evidence gathered during the investigation.

Merritt is also asking he be allowed to examine all physical evidence obtained in the investigation thus far.

Prosecutor Sean Daugherty filed his one-page response to Merritt’s motion on Friday, saying he has already provided to Merritt’s assigned investigator, David Farrell, several thousand pages of discovery, and that he will continue to provide discovery as it becomes available.

Merritt was arrested in Chatsworth on Nov. 5 on suspicion of beating to death Joseph McStay, 40, his wife, Summer, 43, and their two sons, Gianni, 4, and Joseph Jr., 3, in their Fallbrook home, in San Diego County, in February 2010. Merritt is alleged to have buried their bodies in shallow graves in the Mojave Desert, about 100 miles from the McStay home, just west of the 15 Freeway and north of Stoddard Wells Road near Victorville.

Merritt, Joseph McStay’s former business partner who built decorative water fountains designed and sold by McStay, is a former Apple Valley resident who was familiar with San Bernardino County’s High Desert region. Apple Valley is eight miles southeast of where the McStay family’s skeletal remains were discovered by an off-road motorcyclist on Nov. 13, 2013.

The McStays were last seen on Feb. 4, 2010. Their disappearance stumped San Diego County sheriff’s investigators for nearly four years until the family’s remains were discovered in 2013, which marked the genesis of a homicide investigation by the San Bernardino County Sheriff’s Department.

During Merritt’s last court hearing in February, he told Judge Michael A. Smith that he had not seen any of the evidence in the case since his Jan. 30 hearing, which was when Daughtery announced he had just turned over the nearly 10,000 pages of police reports and other documents to Farrell.

The Jan. 30 hearing was also when Merritt requested, and was granted, permission to act as his own attorney.

Merritt suffers from congestive heart failure and fears he may die in custody without having a chance to present his side, his former attorney, Robert Ponce, said following the Jan. 30 hearing. Merritt’s medical condition aside, Ponce said he did not have the time or resources to defend Merritt, as the case was so extensive and voluminous it would have consumed all of his time.
