The Philadelphia 76ers' internal probe on several Twitter accounts linked to Bryan Colangelo have become increasingly focused on his wife.

The release of privileged information and attacks of current and former employees has left ownership of the 76ers embarrassed and angered. Sources say Colangelo is fighting for his professional life.

Colangelo has discussed with ownership and upper management the possibility that his wife, Barbara Bottini, may have been involved in the postings of the tweets from so-called burner accounts.

Ownership has seen little, if any, inclination to separate Colangelo's culpability should a family member or close associate be proven responsible for the postings.

Ownership fears that Colangelo's credibility inside and outside the organization may be too badly damaged to continue his job.
