Garner, N.C. — Garner police searched the Verizon Wireless text messages of the boyfriend of Mayela Orduna for clues to her death, according to a search warrant returned Monday.

Orduna was found unconscious on the shoulder of Aversboro Road near Old Scarborough Lane last week and later died. Preliminary autopsy findings, released Thursday, indicate that she died of a head injury consistent with exiting a moving car, Sgt. Chris Clayton of the Garner Police Department said.

Police searched the text messages of her boyfriend, Spencer Bolick, for "information and insight into the incident" that lead to her death, the warrant said. Police return search warrants to a court clerk after they have executed them, and they are public unless sealed by a judge.

Bolick told police that Orduna attended a party at his apartment, at 3200 Madison Farm Court, Apt. 102, before her death. He said the two argued at the party, then left in his 1993 Crown Victoria.

He said Orduna jumped from the car as he drove along Aversboro Road. According to the warrant, Bolick was on the phone with another party guest, Tara Rich, when Orduna jumped.

Bolick and other party guests "fabricated a story of how the incident occurred in order to avoid responsibility for the victim's injuries," the warrant says.

Police also searched Bolick's apartment and car as part of the investigation and seized marijuana, drug paraphernalia, two purses, a bra, paperwork and an empty pill bottle with white residue, according to a search warrant.

Police are investigating the case as a "suspicious death," Clayton said.

"The (Wake County District Attorney's Office) will make the decision on what, if any, charges are appropriate," he said.
