GREENVILLE -- Documents obtained by News 8 from the Van Zandt County District Court show investigators learned in mid-January Michael Moore's DNA was found at the crime scene of his grand niece's murder, yet Moore was not arrested until May 7.
Michael Moore is the man suspected of killing his grand niece, Greenville teen Alicia Moore, last November.
The capital murder arrest warrant obtained by News 8 Friday lays out a timeline dating back to the beginning of the investigation as authorities tried to identify the 16-year-old's killer.
Alicia Moore's best friend told investigators last year Alicia said she was going with her great uncle on a trip to Paris, Texas to meet an "unknown guy" on the day she disappeared, according to the document. The best friend passed a subsequent polygraph test regarding the information she told investigators.
Authorities also confirmed in November Michael Moore was the only family member unaccounted for on the day of the murder. Moore told police he was in Grand Prairie the entire weekend Alicia Moore went missing, and his truck was broken down.
On January 18, results returned from a DNA swab of Michael Moore. The results indicated the great uncle's DNA was "consistent" with fluids found at Alicia Moore's crime scene.
Authorities said for months they did not have a suspect in the case and continued to raise the reward money while knowing Michael Moore was the primary suspect.
Michael Moore also revealed during an interview in December, when the DNA was taken, that he had previously been linked to a serial murder case in California.
In 2002, Moore helped police arrest his boyfriend, Kevin Sterling Jones, for the murder of two women near Oakland, according to published reports. Jones later pleaded guilty.
The arrest affidavit says police noted then that "the methods described by [Michael] Moore used in the serial killings in California appear similar to the methods used to kill [Alicia Moore] and dispose of her body."
In late March, detectives obtained Michael Moore's cell phone records, which showed he did not use his phone for 10 hours the day Alicia disappeared. Then, he did not use his cell phone for 16 hours on November 5 and November 6.
Alicia's body was found November 6 in Van Zandt County. Moore's cell phone was "pinging" in the Greenville area on November 6, even though he told police he had not left Grand Prairie the entire time Alicia was missing.
Finally, on April 30, more DNA results came back, excluding all male family members and persons of interest investigators had obtained samples from.
Even as police had all that evidence, Alicia's family did not know. They held a vigil May 2, in a chilly rain, pleading for answers or a tip.
The affidavit was released just before the courthouse closed Friday evening and News 8 was unable to reach Greenville police for comment.
