Mesa police said they expect to recommend a manslaughter charge be filed against a Tempe attorney whose vehicle struck and killed a Dobson High School senior on his bicycle last week.
A test of Keith Alan Moore's blood taken about an hour after the April 2 collision that killed 18-year Yong Jin Kim shows his blood-alcohol content was .226 percent, said Mesa detective Tim Gaffney.
The legal limit in Arizona is .08 percent.
"We are hopeful that the investigation will be completed by late next week and the case will be submitted to the Maricopa County Attorney's Office," Gaffney said.
Bill FitzGerald, county attorney spokesman, said his office has asked detectives to concentrate on the "causation issues that might be there."
"What was the cause of the accident, what are the issues that are there," FitzGerald said. "My understanding is they are doing a lot of measurements where the different parts of the crash scene were, where the car was, the speed he was going, where the individual who was killed was going."
Gaffney said Moore had the green light and was traveling west on Guadalupe Road about the speed limit when Kim rode his bicycle north against a "Don't Walk" signal at Rogers Street, which is about a quarter mile west of Alma School Road near the high school.
Moore, who has admitted in public documents that he is an alcoholic, had his 10-year-old son in the car with him and three bottles of vodka that had been opened.
Gaffney said that for a 150-pound man to register a blood-alcohol content of .226, he would have had to drink the equivalent of nine standard drinks. A standard drink is one beer, one shot of liquor or one glass of wine.
Gaffney said he was unsure of Moore's weight.
Officers released Moore to family members after the crash.
Moore did not return a message asking for comment.
