Breakup generates alleged threats from Oklahoma City attorney's assistant

Tiffany Michelle McKinnis, 34, of Oklahoma City, was charged Jan. 30 in Oklahoma County District Court with making obscene, threatening or harassing phone calls, which is a misdemeanor.

A judge set her bond at $50,000.

McKinnis is accused of threatening Assistant Public Defender David McKenzie after he ended a romantic relationship last month with Oklahoma City attorney Holly Hefton.

McKinnis is Hefton's assistant.

Hefton characterized McKenzie as abusive, and said he quit calling her early last month after about a year of dating. She said she was hurt and sad over the breakup.

“She saw how he treated me,” Hefton said of McKinnis. “I think she was just tired of seeing me in pain.”

McKenzie told police he received two phone calls from McKinnis about 4:25 a.m. on Jan. 12, according to a probable cause affidavit.

McKinnis is accused of leaving two voicemails on McKenzie's phone in which she is heard cursing at McKenzie “and telling him she is going to harass him,” according to the affidavit.

“These messages were also threatening in nature,” a police investigator wrote in the affidavit.

The woman also called a third time and hung up, McKenzie said Thursday.

The public defender characterized McKinnis as a “multiple-convicted felon” who “has threatened my life.”

“I think she should be held without bail,” he said Thursday.
