The National Enquirer story seems more than a little iffy... Apparently there's an unpublished book in which Autumn Jackson's aunt said Autumn Jackson said Cosby "might" have got a hitman because Ennis found out about her. If she had any evidence to back this up it's apparently not very clearly spelled out.

Now, The National Enquirer reports that Jackson's aunt, Jewel Star, has written a book entitled Bill Cosby's Love Child that she's currently shopping to publishers.
The book makes the shocking claim that Cosby orchestrated the murder of his son Ennis as part of his attempt to bury the allegations made by Upshaw.
Jackson was arrested just two days after Ennis was murdered by a Ukrainian immigrant with no ties to the 27-year-old.
In the book, Star quotes Jackson as saying, “Cosby might have had Ennis murdered because he had found out about me."
Star says she believes that Cosby sent "a hitman" to murder her as well, but settled for simply having her arrested and imprisoned.
