Horrifying moment Massachusetts advertising agent's lifeless body is DUMPED from his white Porsche SUV and left in DC alley... but police insist there are NO signs of foul play

Washington DC police claim there have been no signs of foul play involved in the death of a 41-year-old man who was dumped from a car and into an alley.  

Shocking footage shows Alan Chen being dragged out of his own white Porsche in a Northwest DC alleyway and being left there dead on November 29. 

The Met Police Department told DailyMail.com that the case is a death investigation and they are waiting for autopsy reports. 

Officials believe Chen's death could be of natural causes and that there were no immediate signs of foul play. 

Video shows the unidentified suspect exiting the white Porsche in a dark alley and pushing the driver's seat forward. 

Once he is able to make enough space, he opens one of the back doors and pulls out the body. 

The victim's feet and arms are seen dangling while the suspect drags his body out of the car. 

Footage then shows him heaving and dropping the body on the side of the alley in the 100 block of W Street.

Chen’s family told Fox 5 that the Massachusetts resident and father of two worked in advertising and sales and would often spend long periods in DC for work. 

'I hope that police or anyone that see[s] this video can find the person that is responsible for what happened to Alan,' his aunt told the channel. 

The family disagrees with the police and believes a robbery was involved in the case. 

A police report says officers only recovered two pairs of shoes, lip balm and blue jeans from the victim's body. There was no trace of his wallet or license. 

'We just don't know why, you know? It's just…society is not safe. So, so many crimes out there. It is just, you know, really, really, really bad,' she continued. 

One DC local in the neighborhood said he had seen many suspicious activities in the alley. 

Manuel said: 'We’re talking a block. Not even a block. We’re talking half a street signal. Unfortunately, what’s happened here before, in this alleyway, it seems to be a thoroughfare and a number – I’ve seen a number of times where I come up at night at somebody is in the car and the windows are all foggy – something’s going on. 

'So, you have to call the police to get them to move or see what’s going on. And it would be great to have more secure lights in the back and such.

'It’s very concerning that something like this would happen in this neighborhood where you’re trying to establish relationships with friends, and then something like this happens where somebody is taken away,' he added.

Police have requested that anyone with information on the Porsche or the unknown driver contact them immediately.
