Capitola Mall stabbing suspect expressed desire to 'kill as many people as possible,' documents show

SANTA CRUZ, Calif. -- A 19-year-old man accused of fatally stabbing a 73-year-old woman outside Capitola Mall on Monday confessed to the killing in a 911 call and later surrendered to police, according to court documents filed by prosecutors.

Prosecutors said the suspect called 911 and admitted to killing Rachel Summers after attacking her as she walked outside the mall Monday afternoon.

According to court documents, the suspect ran up to Summers and stabbed her from behind. Prosecutors wrote that the victim was "stabbed multiple times in her back, defensive stab wounds to her forearms, and stab wounds to her center chest, more than 11 total."

After the attack, the suspect allegedly ran into the mall, leaving a trail of the victim's blood and discarding a knife that prosecutors said he had purchased minutes earlier at a nearby Big 5 Sporting Goods store.

Court documents state that the suspect then went to a nearby gas station, bought a drink and later called police and surrendered.

At the time of his arrest, prosecutors said the suspect told investigators, "He indicated that he had had homicidal fantasies for awhile and that he had previously disclosed these fantasies but he 'kept getting let out' of custody."

The court filing also references a November gun violence restraining order issued against the suspect. According to sheriff's deputies cited in the documents, the suspect had "expressed a desire to cause a mass casualty event."

Deputies also noted that the suspect "wrote a goodbye letter expressing a desire to kill as many people as possible."

Prosecutors argued the suspect should be held without bail, citing the strength of the evidence against him.

"Several eyewitnesses saw the victim stabbed, the defendant confessed, the knives were recovered, and the victim's blood was all over his hands," prosecutors wrote in the filing.

Prosecutors further stated that the suspect "has sustained thoughts and fantasies about murdering someone... and stated in his interview he has had them since puberty."

The allegations and statements are contained in court documents filed by prosecutors seeking to keep the suspect in custody without bail.
