Two people contacted the San Diego police department after reading an advertisement offering a free baby on Craigslist, an online classified ad service. The police obtained copies of the advertisement after being alerted to the possible child endangerment matter.

The ad said: “Free baby boy to good home. My ex-girlfriend had him a few weeks ago, but now he just sits in my closet and cries. I'm not too sure how to deal with it, and I'm in a pretty low financial spot. I lost all the baby accessories. Batteries not included. Transaction final. No returns. Guaranteed not DOA.”
There was also a photograph of a baby, and the information that the baby was in San Diego and would be delivered.

The ad had been removed when the police tried to access it at noon on the same day.

Police involved in the investigation are attempting to trace the person who placed the advertisement.

Judging from the language, I'd assume it was a joke, but I understand that the police have to follow it up. Just in case.
