BARSTOW A Newberry Springs man is due to appear in court Tuesday amid allegations from authorities that he attempted to murder his wife.

David Douglas Knapp, 33, pleaded not guilty to the charge, as well as to charges of making a criminal threat and inflicting bodily injury on a spouse or cohabitant, during his in-custody arraignment last Tuesday, court records show.

Knapp was arrested by San Bernardino County Sheriff's Department officials March 17 on the 46000 block of Fairview Road in Newberry Springs, according to arrest records.

Calls to the sheriff's department and San Bernardino County District Attorney's Office for information regarding the circumstances of the arrest were not immediately returned as of early Saturday afternoon.

It's alleged that Knapp "personally and intentionally discharged a firearm, a rifle" in connection with the attempted murder charge, according to the felony complaint filed last Tuesday by the DA's office.

Knapp is also facing five special allegation charges, including that the "attempted murder is premeditated, deliberate, willful," court records show.

Knapp has no prior violent crime convictions in San Bernardino County, according to court records.

Following his arrest, he was booked at West Valley Detention Center in Rancho Cucamonga, where he currently remains in custody in lieu of $1 million bail, booking records show.
