[Lucius Cornelius Sulla]

He executed Fausta, his wife, some years earlier, by locking her in an overheated bath. They think she had been conspiring against the Emperor with his son, Crispus, whose head he had cut off.

You might be thinking of his mother, Saint Helena, former concubine of the Emperor Constantius I. She died seven years before her son.

Yes, you’re right. His mother. Thank you!

Helena was living when Constantine executed his son, Crispus, in 326. Constantine later renamed a city, Helenopolis, in honor of his mother and was with her when she died in 330, at about the age of 80.

This is according to "Church History" by Church Father Socrates Scholasticus and "Life of Constantine" by Church Father Eusebius Pamphili, Bishop of Caesarea.
