ELIZABETH -- Two more victims of the Nov. 11 house explosion on Magnolia Avenue have died of their injuries, making a total of four people killed in the incident.
St. Barnabas Hospital confirmed today that Tyquan Henderson, 11, died yesterday. His sister Tavasha Henderson, 36, died on Jan. 5, a spokeswoman said.
Another sister, Kimiyha Henderson, 26, also died from her injuries on Dec. 3.
Femi Brown, 24, another resident of the multi-family home, was pronounced dead at the scene.
Elizabeth Mayor Christian Bollwage said previously that the ground floor of the three-story home had been illegally converted into a living unit with gas and electric, and that the explosion was caused by gas.
Sixteen residents in total lived in the home, authorities said.
"I think that any illegal conversion is a crime. The bottom line is greed to bring in more money," Bollwage said.
Elizabeth Police and the Union County Prosecutor's Office are investigating the exact cause of the explosion and no one has been charged yet.
The owner of the house, Abel Brito, of Perth Amboy, purchased the property in 2003 for $360,000, according to city records.
