A man accused of spraying blue graffiti on the Boston Public Library and Trinity Church — who was also charged with arson on Boylston Street in February — was ordered to undergo a mental health evaluation Monday after a recommendation from a court clinician who told a judge the suspect has a “significant delusional belief system.”

Angel Rodriguez, 37, was arraigned in Boston Municipal Court Monday where a not guilty plea was entered on his behalf.

Dr. Jodie Shapiro, a Boston psychologist, told the judge an evaluation revealed Rodriguez had a “significant delusional belief system” which “influences a lot of his thinking.” She recommended Rodriguez’s competency be further evaluated. Rodriguez was ordered to undergo a mental health evaluation at Bridgewater State Hospital before bail is set and will be due back in court March 28.

Rodriguez’s court-appointed attorney Shannon Dale declined to comment on the specifics of the case or her client after the arraignment, only telling reporters “he’s doing OK,” when asked about his state.

According to police, Rodriguez was arrested Saturday morning on a charge of malicious destruction of property after officers responded to a vandalism in progress and stopped Rodriguez, who was in the area of Commonwealth Avenue and Dartmouth Street. The officers smelled fresh paint coming from Rodriguez’s clothes and saw blue paint on his jacket.

The graffiti, tagged on multiple parts of the buildings, read, “Wash DC rapists Epstein/Clintons,” “Google: Jeff Epstein,” and “xxsick.”

According to an incident report, officers asked Rodriguez what his spray paint can was for, to which he responded “I work for the government and people need to know about Jeff Epstein.”

Rodriguez also told police, “I was doing graffiti in this area earlier and I was walking home.”
