The personal phone number of the professor, Samuel See, was reportedly listed advertising Ryan Cochran Escort Services in New Haven. As The Register reports:
The website Ryan Cochran Escort Services includes the same phone number listed on an order of protection filed against See in September. A profile photo on the Ryan Cochran Escort Service website matches the profile photograph on a LinkedIn account purporting to be See's. The website lists Cochran's home city as New Haven. A Facebook page with pictures resembling See and listed under the name Ryan Cochran includes See's home address.
The Register was unable to confirm what kind of connection - if any - See had to Ryan Cochran Escort Services.
See's
Below is a screenshot of See's LinkedIn profile - which reportedly uses the same profile picture as the Ryan Cochran Escort Services website. The Ryan Cochran Facebook account [link includes NSFW images] includes See's reported address.
