CHICAGO (CBS) — Relatives said the man who killed two women and injured two men before killing himself in the Ashburn neighborhood on Monday suffered from mental health issues, and got into a fight with his girlfriend a day earlier when she ended their relationship.

LaQuisha Hickman, 37, reportedly told her boyfriend Edward Prince she was ending things Sunday night.

When police were called to Prince’s uncle’s house in in the 3500 block of West 79th Place on Sunday, because Prince and Hickman were fighting, Prince already had left. Still, Hickman filed a domestic battery report against him.

He returned to the house Monday morning and went on a shooting rampage shortly before 9 a.m.

Relatives said Prince, 36, took at least 10 people hostage in the house. He pistol-whipped his 58-year-old uncle, and shot an 18-year-old male cousin in the leg.

Those two men escaped the home with non-life-threatening injuries.

As police arrived at the scene, responding to reports of shots fired, they found those two men outside the home, and heard shots fired inside.

Relatives said Prince shot and killed Hickman in a jealous rage, then shot 23-year-old family friend Nicole Loving, before turning the gun on himself.

Neighbors said at least 80 police cars and vehicles swarmed the area after Prince apparently fired shots at arriving officers.

“Right now, we’re all shook, be we don’t understand it. I don’t understand it. I’m the oldest cousin, and everybody looking at me for [answers] and, right now, I don’t have ’em,” said Prince’s cousin, Sheila.

Relatives said Prince had suffered from mental health issues before the shooting, but it was unclear if he’d stopped taking his medication.
