ANCHORAGE, Alaska - An Anchorage teen who ran over a cyclist with a pickup truck and drove away will appear in court Friday for a sentencing hearing.

Documents filed ahead of the hearing provide details about the case and show that the girl may have been intoxicated, reported KTUU-TV (http://bit.ly/1L5U2EE ).

Alexandra Ellis had just taken a friend home from a large party she hosted while her parents were out of town when she hit 51-year-old Jeff Holder-Dusenbury, according to the documents.

The July 2014 crash left the avid cyclist dying on a quiet residential street on a Saturday morning.

The judge in 18-year-old Ellis' case will decide whether to accept a plea agreement reached by state prosecutors and defense lawyers. That deal would put the teen behind bars for one to three years for negligent homicide.

Her lawyer, William Ingaldson, has asked the judge to consider putting Ellis in the juvenile system until she is 20 years old. Ellis was 17 at the time of the crash.

But the Office of Victims' Rights argues that Ellis should not be treated as a juvenile. In a document filed with the court, the office says the teen, who was fresh out of a substance abuse treatment program, held a wild party while her parents were in Talkeetna.

"Ellis and her guests played beer pong, drank alcohol, and used Ecstasy and other drugs," according to documents. "Ellis admitted to taking 'Molly' (also known as Ecstasy), but admitted to Providence hospital staff that she had also used cocaine the night of the party."

Alcohol and the active ingredient of marijuana were also later found in her system.

Ellis was released from the substance abuse program eight days before the crash, according to Office of Victims' Rights.

Ingaldson said Tuesday that the program was meant to curb Ellis' use of Adderall, a stimulant prescribed to improve focus that is sometimes abused.

After dropping her friend off around 10 a.m. the next morning, Ellis started driving in reverse.

The teen passed a side street where she could have turned around, but her lawyer says she drove past it because her flip-flop was jammed beneath the accelerator. He says she was going 11 or 12 miles per hour.

"It's not such a clean case," said Ingaldson, who contends that Dusenbury , the cyclist, was traveling at 30 or 35 mph and was actually the one that hit Ellis. He also argues that the cyclist was wearing headphones and likely in the middle of the road, in a spot not visible to the driver of the truck.

Ellis' truck traveled 40 feet after colliding with Dusenbury. She then sped away.

Police later arrested her at her house.

Her blood alcohol content was .101 in a sample collected at 12:51 p.m., according to a report from the Alaska Scientific Crime Detection Laboratory. That is above the .08 limit to drive; however, her attorney says she passed three field sobriety tests.

"Most people that have been drinking the night before get up and think you're still intoxicated," Ingaldson said. "There's some real issues of whether this was caused by intoxication. I don't think it was. I don't think, if she had nothing to drink, that she would have done anything different."

The laboratory also found THC -- which indicates marijuana use -- in both Ellis' system and Dusenbury's.
