Police say he used that same weapon to attack everyone he saw, including a fourth woman, 29-year-old Candace Murray.
According to police, Vanderhall was found sleeping in a auto within two miles of the crime scene and was arrested, police say.
Sunday morning he will be arraigned on three counts of murder and one count of attempted murder.
Using a hammer, the suspect allegedly beat and killed his mother - 58-year-old Lynn Vanderhall, his sister Melissa Vanderhall, 29 and Janel Simpson, 29 - allegedly striking them all multiple times with a hammer.
Authorities said Vanderhall's behavior had become more troubling recently, leading his mother to obtain an order of protection against him.
"When he came here last night and it looked like the doors were secured, he became enraged", Fitzpatrick said.

The heavier and more extensive rain areas will move east tomorrow night with some rain lingering overnight. Expect high temperatures to rebound back into the 70s, 80s and 90s statewide.
Vanderhall had been kicked out of his mother's house and was homeless, according to Lt Stephen Fitzpatrick of Nassau County homicide.
The survivor, who wasn't identified, was hospitalized in stable condition. He took a framing hammer from the garage, broke into the home and attacked the group of women, according to police. "Beautiful, outstanding people, that's what I want the world to know", said a family relative, Juanita Johnson. He described his daughter and her friends as fun-loving women and said they were even planning to go to Cuba in the fall.
Bobby Vanderhall, 34, was charged with murder in the deaths of the three women after police found him sleeping in a vehicle nearby.
'These girls don't give problems, these girls just have fun, ' Simpson said.
