Prof to 911: Student Who Died Did Coke

May 16, 2008— -- A Phoenix professor whose student died after a social visit to the professor's condo told a dispatcher on the morning of her death that the young woman had been drinking and doing cocaine in his living room before he found her unconscious on his couch.

Andria Ziegler, a 19-year-old psychology student at Paradise Valley Community College, died at a hospital after paramedics responded to a 911 call placed by Michael Todd at 2:34 a.m. Sunday, April 20. The 51-year-old academic, who has since lost his professorship, had taught Ziegler for the two semesters prior to her death.

"We sat around [pause] while she did some coke," Todd told a dispatcher in the eight-minute call, which was released Thursday by Phoenix police after a Freedom of Information Act request. "And I went upstairs and went to bed."

"Apparently, she kept using," Todd, his voice quivering a bit, continued. "I come down about an hour and a half later, she was unconscious."

Todd's neighbor, identified as a woman named Pat, can be heard in the background calling to Ziegler to wake up. The dispatcher, who remained on the phone with the pair as they attempted to revive Ziegler, walked them through a sternum rub and mouth-to-mouth CPR. Todd's neighbor said she felt a slight pulse, saw some rising in the woman's chest and could hear gurgling as Ziegler attempted to take small breaths. Todd told the dispatcher he does not see any of that.

"Her lips are starting to turn a slight bit blue," Todd said.

The dispatcher asked Todd who the unconscious woman is. "That's Andria," he said, describing her as "just a friend."

The dispatcher asked whether Ziegler had been drinking and Todd proceeded to count 17 empty beer cans -- of which he claimed he drank just one.

Initial autopsy results failed to show an exact cause of Ziegler's death. Sgt. Joel Tranter, a spokesman for the Phoenix Police Department, said that authorities were eagerly awaiting toxicology report results, which he described as key.

Detectives from both the department's homicide and sex crimes unit are looking into the case. Todd is not considered a suspect in any crime because the cause of Ziegler's death remains unknown. Todd is, however, "obviously a person of interest" in the investigation, Tranter said.

The investigation got off to a difficult start in part because Ziegler arrived at the morgue from the hospital as a "Jane Doe," or unidentified female. Todd did nothing to confirm her identity for rescue personnel or doctors.

Ziegler's family, concerned when she did not return from a night out Saturday, began searching for her that Sunday and ultimately filed a missing person's report around noon Monday.

Authorities matched Ziegler's description provided by the family with the unidentified woman who had arrived at the morgue the previous day.

"Am I angry? Of course I'm angry," Dick McManus, Ziegler's stepfather, told ABC News today about the release of the 911 calls.

"He has no emotion in his voice," McManus said. "He's sounds like it's been made up or it's well thought out. He says Andy's been doing coke. What was he doing? Oh, he was busy watching her do coke and then he goes to bed?"

After Ziegler went missing, he tried to reach out to Todd by phone and e-mail and ultimately drove over to his condominium, where he found his stepdaughter's car.

McManus said at the time of Ziegler's death that his family, which includes seven brothers and sisters, believed that Todd had been trying to win a date with his stepdaughter for weeks.

Since her death, Ziegler's family learned that she had been at Todd's house the Wednesday before her death, McManus said.

Reports have surfaced about potentially inappropriate relationships between Todd and his female students. In 2002, Paradise Valley Community College required that he take an online sexual harassment course after a report about his behavior. On May 8, the chancellor of Maricopa Community Colleges, a group that includes Paradise Valley belongs, recommended his termination for violating the school district's "amorous relationships" regulation.

Todd has declined to comment. His attorney, Michael Roth, did not return a phone call from ABC News about the 911 call. After the death, Todd released a short statement through his attorney: "Mr. Todd, as well as everyone here at Roth and Roth would like to extend our prayers and condolences to the family and friends of Andria Ziegler during this tragic time."

His condominium was ultimately searched as a crime scene, but because of the time lag connected to her "Jane Doe" status, Tranter said that the evidence collected may have been compromised.

Ziegler's family, while satisfied with the police investigation, remains unsatisfied with Todd despite his job loss. "This guy is a sexual predator," McManus said. "I hope he's locked up. Justice will be served."
