A man with a history of “emotional issues” was arrested Saturday for bludgeoning his mother, his sister, and another woman to death in Hempstead, New York, multiple reports said.

Bobby Vanderhall, 34, was accused of breaking into his mother Lynn Reichenbach-Vanderhall's house and through the basement door and beating his mom before doing the same to his sister, Melissa Vanderhall and her friend Janel Simpson, one of the women visiting the house.

According to Nassau County police, Bobby entered the house on Perry Street at around 1:15 a.m. ET Saturday, and took a hammer from the garage. He then broke in through the basement and found his 58-year-old mother in the kitchen where he beat her with the hammer until she died, said reports.

He found Melissa and a second friend of hers on the staircase and hit them too. However, the latter managed to escape and flagged down a passer-by who called Hempstead police for help. Meanwhile, Bobby killed her sister's other friend Janel, who he found in a room upstairs, in the same manner.

“When he came here last night and it looked like the doors were secured, he became enraged,” said Lt. Stephen Fitzpatrick, commanding officer of the Homicide Squad. “He went to the garage. He obtained a large hammer. … With this framing hammer, he broke through the basement door," he told Newsday.

Police also told journalists that the three women died from“blunt force trauma.” The fourth woman who escaped has not been identified. She was hospitalized to be treated for wounds from the attack.

Fitzpatrick revealed Bobby was homeless after he was recently kicked out from his house by his mother because of his troubling behavior and emotional issues. His mother had even obtained an order of protection against him.

The police described Bobby as more than six feet tall and at weighing least 230 pounds. He was arrested after the police found him asleep in a car, two miles from the house. It was revealed he had a history of mental problems and a criminal record that included sexual abuse charges and DWI.

"The family right now is distraught," said Juanita Johnson, a cousin of the Vanderhalls to NBC New York. "We in shock."

Janel's father Dennis Simpson told the network that his daughter was a secretary at Northwell Health, a chain of healthcare facilities and used to work late hours. She went to her friend's place to hang out. He described his daughter and her friends as fun-loving women and said they were even planning to go to Cuba in the fall. "These girls don't give problems, these girls just have fun," Simpson said.

Bobby has been charged with three counts of second-degree murder and one count of attempted murder. He is scheduled for arraignment on Sunday and is currently being kept in Mineola in Nassau County.
