Brett Anderson Quits Job to Stay In 'Safe and Familiar' San Diego with Daughter Hannah

"I'd hoped that Hannah would be able to return to Nashville with me, but I agreed that it was important not to uproot her at this time from everyone and everything she knows and finds to be comfortable, safe and familiar," Anderson tells PEOPLE in an exclusive statement.
"There is no way I will give guardianship of my daughter to anybody – she needs her father and I need my daughter."
"As a result, I called my company today and informed them of my decision to move back to San Diego, and my resignation," continues Anderson. "Hannah and I will be moving into a home together, and she is as excited as I am to be a family and continue our healing together."
DiMaggio is suspected of killing Hannah's mother, Christina Anderson, and her 8-year-old brother Ethan, whose bodies were found Aug. 4 in DiMaggio's burning house in California near the Mexico border, and abducting Hannah before her safe recovery Aug. 10.
Investigators have said DiMaggio set fire to his home using a timer, giving him a 20-hour jump on law enforcement.
Authorities have declined to discuss a possible motive in the deaths and haven't addressed other details of the case, including how Hannah was treated by DiMaggio during the ordeal.
