The 4-year-old boys have been staying with Mueller's brother Scott since Denise Richards was forced to give them up after she had a violent outburst toward her daughters Sam, Lola and Eloise, but now, authorities are considering taking the kids from their uncle.
“There is a very real possibility that Bob and Max could be placed in foster case because evidence was also uncovered regarding their temporary guardian, Scott, that is riddled with glaring differences in version of events,” a source close to the situation told Radar online.
“The department is taking this very seriously, and are considering recommending the boys be placed in foster care, pending the outcome of the investigation."
The source added that Sheen couldn't get custody of the boys given his past behavior and that Mueller's parents won't even be considered.
"It’s such a sad situation, but the safety and well-being of the boys comes first. Such drastic action wouldn’t be taken unless it was necessary, and sadly, it is,” said the insider.
Mueller lost custody of her sons last summer after she was placed on an involuntary psychiatric hold over her drug abuse. She was scheduled to get the kids back by Christmas before the new information regarding her treatment was uncovered.
