Police are hunting for a woman who fled to Thailand following a fatal hit-and-run on New Year's Eve.
Ben Kable was walking home from a New Year's party on January 1 at around 6am when he was hit.
Authorities claim that Tubtim 'Sue' Howson, a mum-of-two, ran away to her country of birth just days after the fatal crash to escape prosecution for the 22-year-old's death.
According to Ben's dad he had been thrown out of an Uber on a dangerous stretch of road with no streetlights, pavement or even hard shoulder.
Howson, from Michigan in the US, was born in Thailand but is now a US citizen. Records show she bought a one-way ticket from Detroit to Thailand, landing on January 5.

She faces charges of failure to stop at the scene, resulting in serious impairment or death, and now the FBI now say there is probable cause to charge her with felony interstate flight to avoid prosecution.
Ben's dad Michael Kable said 'When she kicked him out, it was on Rochester Road, a very bad spot.
'There's no streetlights, there's no sidewalk, you know, very minimal of any shoulder."
The victim, a senior at Michigan State University, texted a friend to say 'Looks like I'm walking from here' shortly before being hit.
Witnesses on the scene said the suspect stopped for a short time before fleeing.
The newly-unsealed FBI complaint says Howson "allegedly told a close associate after the crash that she thought she killed somebody and was going back to Thailand.
"When encouraged to turn herself into police, Howson allegedly stated, 'no cops, no cops.'"
Oakland County Sheriff Mike Bouchard has called for an extradition "so we can hold her accountable for her actions involving this young man's tragic death."
Michael Kable told FOX2: "Just the lack of empathy and humanity it would take, and then just plot your getaway.

The grieving dad continued: "It is hard to fathom how somebody can leave someone dying on the road
"Just no empathy... I don't understand it."
A GoFundMe set up in the wake of Ben's death read: "Benjamin loved hunting, fishing, playing video games and spending time with his friends and family."
"He was a gentle soul who you could always rely on and was always there if you needed a shoulder to cry on or someone to talk to.
"If you ever needed a good laugh, Benjamin was the person you would turn to."
