Investigators are building their case against Justin Ross Harris and his wife, Leanna, may be their next target.
"Clearly she's the subject of the investigation," said Ken Hodges, a former prosecutor.
Justin Ross Harris is accused of leaving his son, Cooper, to die inside a brutally hot car.
Leanna Harris, the 22-month-old boy's mother, has not been charged, but she has hired Atlanta attorney Lawrence Zimmerman.
Zimmerman told The Associated Press he couldn't comment about his role in the case.
"If someone has legal problems they should have one, especially in a situation like this," Hodges said.
If investigators are considering charges against Leanna Harris, she could face the same consequences her husband may face.
"If she's a part of the murder, then she's facing life in the penitentiary as well as, possibly, a death sentence," Hodges said.
Investigators have said that the couple researched online how long a child could last inside a hot car, logged onto sites for people who don't want children and that Leanna Harris told them she feared her son being left in a hot car, but said nothing of the fear of losing her child.
"With her going on these websites regarding leaving children in cars and if she went on the other websites regarding being a childless parent, those would all be strong indicators that she was involved," Hodges said.
Meanwhile, the online payment site PayPal says it will give refunds to people who donated to a fundraising campaign for the family. A PayPal spokeswoman told The Associated Press the company will soon be issuing refunds to customers who used PayPal to donate to the campaign at YouCaring.com, where a total of more than $22,000 was given.
