It's been a year since the remains of 17-year-old Maggie Long were discovered inside her burned home in Bailey. Incoming Park County Sheriff Tom McGraw said he plans to re-evaluate the investigation within two weeks of taking the reigns on Jan 8.

KUSA — Park County Sheriff-elect Tom McGraw said investigating who murdered 17-year-old Maggie Long one year ago is one of his "top priorities."

Long's remains were found inside her burned home in Bailey on Dec. 1. In those 12 months, no suspects have been named in the case. Outgoing Park County Sheriff Fred Wegener also called the case priority No. 1 at the time.

McGraw said he plans to connect with other agencies that are working on it within two weeks of taking the reigns from Wegener and being sworn into the position Jan 8.

"Obviously what is going on is not working," McGraw told 9NEWS. "I have it as one of my top priorities."

He also said he has not yet been briefed on the status of the investigation.

"Hopefully we might be able to produce some information to the public and see if there is any new information out there that the public has that we can use," he said.

On Dec. 1, 2017, Maggie Long had plans to attend an evening concert at Platte Canyon High School. She left school and did not return. Her car was found at her family’s home off County Road 43. The home had been set on fire, and the Park County Sheriff’s Office said it was clear there had been a burglary, but didn't elaborate.

Days later, the sheriff's office announced they found Long's remains inside of her burned home and announced the teen was killed on the last day she was seen, sometime between 3 p.m. and 7 p.m. on Dec. 1.

For months, there was little to no movement in the case. No suspects were named. No motive was announced.

The first time a news conference was held addressing Long's death was in February - more than two months after she was found dead. There, the sheriff's office and state and federal investigators appealed to the public for information that might crack the homicide case and also announced a reward increase from $15,000 to $20,000.

Photographs of a green safe, a Beretta 9mm handgun, an AK-47-style rifle and jade figurines that were taken from Long’s home were shown.

Although the pictures were released, Wegener declined to release other information during the press conference – including how Long was killed and whether she was sexually assaulted – because he said it could compromise the investigation.

Sheriff Wegener continued to insist the public was not in danger despite acknowledging that his department has no strong suspects in the murder and that the killer apparently made off with an AK-47-style semiautomatic rifle, a semiautomatic pistol and approximately 1,000 rounds of ammunition.

“I guess you have risk and threats every day,” Wegener said at the time.

In May, the sheriff’s office released a sketch of a man they said was seen at the Long house, but stopped short of calling this person a suspect.

Since then, there hasn’t been a formal update on the investigation.

McGraw said he believes the current investigative team is "doing everything they can to move this investigation further."

"Sometimes in a homicide investigation when you get some news eyes on it and some new ideas you can get some new information," he added. "We might have to start all over again and re-interview everyone in the case."

McGraw said he was bothered that the public wasn't asked to help out early on in the case.

"It was kind of kept in house," he said. "I have used public and social media quite a bit and sometimes you get good results and sometimes you get nothing."

Long would have been approaching her 19th birthday next month.
