Jacob Sowell’s nap was rudely interrupted on Monday afternoon by the scene outside his sixth-floor apartment window. He was shocked by what he saw — smoke and a baby dangling out of the window.

“It was almost like a dream – a bad dream,” the 66-year-old Sowell said.

What he saw was Vanessa Scott, 18, holding her 7-month-old cousin, Zaniwah Alexander, out of the window of her fifth-floor apartment that was engulfed in smoke. She was trying to keep the baby from suffocating, she later told the Daily News.

Sowell heard Scott scream, “the fire’s up on me.” Meanwhile, voices from the crowd below cried, “don’t drop the baby!”

From Sowell’s window, he could see that she was loosing her grip.

Just after 2 p.m. at 795 Pelham Parkway North, a fire broke out in a fifth-floor apartment. Ignited in a closet by the front door, the flames soon spread through the crowded apartment, sealing people in a thick curtain of flame and smoke. Tenants raced to the windows for air.

In the apartment directly above, Sowell called 911 and then, with his 20-year-old son Jacob, rushed to the window in his son’s bedroom. Below them, a man and a woman were leaning out the window, gasping for air. “How can I help?” Sowell wondered.

Sowell, a construction worker, seized his safety harness and then broke the bedroom window. He clipped the harness to a pipe nearby and handed the makeshift tether to the man below, who grabbed it and was able to lean farther out.

Within minutes, fire trucks arrived. The firefighters extended a portable ladder and set it against the seven-story building. One climbed up and carried the baby down to safety, then began to evacuate the other people.

The rescue did not come in time for Michel Alexandra to avoid injury. He had been hanging from a rope out of the apartment when the firefighters arrived. Then he lost his grip, falling four stories and striking the building’s awning before hitting the ground. He was evacuated to Jacobi Medical Center, where he is in fair condition, hospital officials said.

Firefighters rescued eight tenants, who were also brought to Jacobi with minor injuries. They have since been released. In addition, three firefighters were treated for minor injuries.

A day later, many residents of Pelham Parkway Houses were still shaken up.

Betty Diaz, 51, whose apartment is on the same floor as the fire, fled the building when she heard the screaming of her neighbors. By the time she snatched Kiuruba, her Yorkshire terrier, and left her apartment, the choking, black smoke filled the hallway.

“I can’t see, I can’t even breathe,” Diaz recalled.

Diaz, who has lived in the building for 36 years, said this was the first fire.

The cause of the fire was children playing with matches, Fire Department officials said.
