DELPHI, Ind.-- Indiana State Police (ISP) said Thursday a man arrested in Colorado is now considered a "person of interest" in the murders of two Delphi teenagers.
"It is quite uncanny on how similar his features are to the sketch," said Libby's grandma Becky Patty.
Daniel Nations, 31, was arrested Monday in Colorado after police say he was driving with expired Indiana plates. He's also accused of threatening people with a hatchet on a Colorado trail.
FOX59 News spoke with authorities in Colorado who said Nations was arrested near the same trail in Colorado where a bicyclist was shot to death two weeks ago. No arrests have been made yet in that murder.
Wednesday night, ISP said they were looking into Nations' case and said they've received thousands of photos of people who may look like the Delphi suspect sketch.
"It is not just him that we are looking at but all of the cases and pictures that we have received..we do the same thing," said Indiana State Police Sgt. Kim Riley.
On Thursday, ISP called Nations a "person of interest" in the murders of Abby Williams and Libby German, but did not elaborate further. The girls were killed after walking along a trail in Delphi; the suspect came up behind them and told them to go "down the hill" before they died.
Nations is a registered sex offender and has convictions for domestic battery and drug possession.
"We are going to check to see what his location was at the time of the murders back in February. If he was not in the state of Indiana at that time...that will pretty much clear him out," said Sgt. Riley.
"We are aware of the arrest of Daniel Nations and have been told by law enforcement that he is being looked into. We pray that the truth will be revealed and we will keep searching for answers and passing out fliers until Abby and Libby's killer is behind bars," said Libby German's grandmother, Becky Patty, on Wednesday.
"There is hope. We want this to be over and in one sense we want this to be him so we can move onto the next chapter of this story," said Patty.
Nations is being held in the Teller County Jail. He was originally only charged with possession of a weapon by a previous offender, but felony menacing and reckless endangerment charged were later added.

He was also booked into Morgan County Jail on Feb. 24, 10 days after the Delphi killings. Nations was booked for Failure To Appear at a civil suit.
