Before she was fatally strangled on Saturday night, Maine mother Kimberly Mironovas, 47, allegedly survived a previous attempt on her life and didn’t even know it.
According to media reports on Mironovas’ killing, Maine State Police investigators allege she was killed by her teenage son, who, they claim, enlisted the help of two friends to strangle and stab his mom in the neck while she slept, the Kennebec Journal reports.
Citing court records, the Bangor Daily News reports the son is being held without bond on charges of intentional or knowing murder and criminal conspiracy to commit murder. (PEOPLE is not naming the son or the other suspects because prosecutors have not yet determined whether they will be charged as adults.)
Police allege the son and the same two friends attempted to murder his mother previously. The trio allegedly crushed up pills they put into her wine, but she did not die.
