AUBURN, Mass. (MyFoxBoston.com) -- It's been five days since two young foster children went unresponsive at an Auburn home and one of them passed away. Investigators have yet to say how 2-year-old Ava Conway Coxon died and what left a 22 month old clinging to life.
Coxon's loved ones attended a wake Thursday night, to say goodbye.
No one faces any charges and investigators still have not released a cause of death. They say they're waiting for the results of toxicology reports.
They have searched the Auburn duplex three times, but have released limited details about what they're looking for and why.
The children's foster mom, Kimberly Malpass, is now at the center of a DCF investigation. No ones knows, at least publicly, what happened to the two young girls. The foster mom's sister told us this week that her family want answers too, and she defended Malpass.
"My sister is an amazing person what's in her heart is that she's taking in these children to be there for them and let them live in her home and be normal and have the best life until they can be reunited with their parents," Tamari Malpass said.
Sources tell FOX25 that investigators are looking at whether overheating contributed to the death and injuries. In addition to searching the home, they immediately towed away Malpass's SUV.
Ava's biological family has railed against the state for their handling of the little girl's case. Her mother has been in and out of drug rehab, but the family says they were fighting to get her back.
Her biological father, David Coxon, said, "All I want is answers, true answers."
