A Mississippi teenager accused of having sex with a German shepherd has been pictured with the dogs days before her arrest.

Denise Frazier, 19, was snapped with the dog after crashing her car in Myrick, Mississippi last Sunday - days before she was arrested over a clip of the alleged bestiality.

Cops have also since revealed that the alleged dog sex clip was shot outside a Baptist church in Frazier's hometown.

She was allegedly caught on a video that had spread around via Snapchat depicting having sex with the male canine in a local church parking lot, it is claimed. She could face up to ten years in prison.

The investigation has revealed further disturbing details about Frazier's dalliances with dogs, which she initially claimed she was forced to do but police say there is no evidence of that being the case. 

A total of three dogs were seen on the bestiality clip, but it's unclear if Frazier is accused of abusing the others. 

One of the videos appeared to have been filmed in the parking lot of Freedom Baptist Church Myrick, Sergeant JD Carter said. 

The Mississippi woman who was arrested after a video posted to social media allegedly showed her having sexual intercourse with a German shepherd was allegedly on camera with three separate dogs, according to police

Screenshots of iCloud-shared shots from the videos showed these being filmed from February 23 through 28.  

Carter's investigation led him to suspect that Frazier was doing this willfully with three separate dogs. 

All three dogs are currently being treated at a local animal hospital, according to WDAM. 

A concerned resident flagged the video from February to local authorities and she was eventually arrested on aggravated cruelty charges. 

'In my 17 years in law enforcement, this is one of the most disturbing cases that I've ever investigated,' said Sergeant JD Carter of the Jones County Sheriff's Department. 

'JCSD is in possession of several videos that are so graphic that we are not at liberty to release them or even discuss the particular content,' he added. 'The investigation into this case is far from over.' 

Frazier did admit that it was her engaging in sexual intercourse with an animal on the video, it has been claimed, although DailyMail.com has yet to verify this admission. 

Carter says that Frazier's alibi was that she was forced into committing the heinous acts but says there's no evidence of that though they are investigating.
