Man murders his mother, sister and her friend with hammer

A deranged Long Island man, left on the street since his mom evicted him, returned home Saturday to execute her, his sister and a third woman .

Bobby Vanderhall, 34, was sleeping peacefully inside a parked car when he was arrested about 2 miles away from the Hempstead home where police say he carved a late-night trail of terror.

He bashed all three women to death with a hammer in the suburban two-story home where he lived until Lynn Vanderhall gave her only son the boot.

“He came to kill mom and the sister because his mother had kicked him out,” said Stephen Fitzpatrick, head of the Nassau County Police Homicide Bureau.

 The killing spree started shortly after Bobby returned to the house in the middle of the night, only to find he was locked out.

“The doors were secured and he became enraged,” said Fitzpatrick. “He went to the garage, he obtained a large hammer. With this hammer, he broke through the basement door.”

Once upstairs, he fatally bludgeoned his mother in the living room before heading toward the second floor. He was climbing the stairs when his sister and Murray appeared, rushing down to help Melissa’s mom, police said.

 Bobby began bashing his sister as Murray fled for her life. Janel Simpson was by herself in another room, where Bobby Vanderhall killed her last, cops said.

The third victim, identified as a friend of his sister, was simply in the wrong place at the wrong time, as was a fourth woman who escaped after watching the 6-foot, 234-pound Vanderhall smash his sister Melissa in the head with the oversized hammer.

In addition to Lynn Vanderhall, 59, and daughter Melissa, 29, police identified the other victim as Janel Simpson, 29. Janel and Melissa were best friends since childhood.

According to police, the slain mother had an order of protection against her mentally-troubled son — who now faces three counts of murder and one of attempted murder.

The order did not bar him from the home, only from harassing his mom.

Lynn Vanderhall threw her son out of the house at some point after a March 2017 incident where he was accused of slapping and physically harassing her, police said.

“His behavior became more unruly, more violent,” said Fitzpatrick. “His mother had enough.”

He was twice hospitalized for emotional issues, and had a rap sheet that included a 2003 DWI arrest and 2015 bust for forcibly touching a woman.
