MILWAUKEE (CBS 58) -- Those who knew the victims who died in Sunday's fire near 27th & Highland are left heartbroken by their losses. Others are wondering when they will be able to return to their units to gather their belongings. 

On Mother's Day, five people died, several were hospitalized, and dozens were displaced because of the fire. 

Those who died included 32-year-old Shakwanda Harris, 40-year-old Torrell Coleman, 62-year-old Verna Richards, 76-year-old Mark Chaffin, and 67-year-old Maureen Green. Green's friend, Monica Shelton, is heartbroken over the circumstance surrounding Grene's death, she's remembering happy memories together. 

“I’ve been knowing her for 22 years," Shelton said. “I’m just in disbelief this happened to her, it’s unbelievable. What makes me not feel sad about this thing is because I remember her joy, her laughter, and how she made everyone that she knew feel.”

On Wednesday, May 14, people like Pedro Sarcerio went back to the Highland Court Apartments to try to gather their belongings. Sarcerio says he has no idea when he'll be able to see what survived the blaze. He said he was hospitalized due to the smoke from the fire. 

“I feel sad, angry and depressed," Sarcerio said. “I’m in the dark, every person I talk to, they give me a different story. I don’t know who to believe.”

While people grieve, investigators are working the scene, trying to figure out how the fire started and whether it was intentional.

Milwaukee Fire Chief Aaron Lipski said at a Tuesday afternoon media briefing, "There's a lot going on here. A lot of dynamics. We can't rule anything out. With such a huge loss of life, it's just critical we get it by the numbers."
