ST. PETERSBURG, Fla. — Two communities in St. Petersburg are reeling from the recent murders of four people. On Wednesday, the city's top cop hit the streets with officers and civic leaders to reassure those communities and to continue the investigations into two of those crimes.

The mother of one of those victims is banking on police to get that one tip they need to make an arrest. 

Qwanda Anderson fought back tears as she described her 19-year-old son, Malik Oliver. 

“He was a very humble person. He was a very sweet person," she said. "He didn’t bother anybody. He wasn’t a fighter. If you asked him to do something he would do it."

Police said they found Oliver’s body in an alley off 13th Avenue South last month. A day later, they found a burned car they believe is linked to his murder. 

But there have been no arrests. His mother wants justice.

“I’m a mother. I lost a child," Anderson said. "When they catch them, I’m never going to have closure. My heart is always going to be broken."

"That was my first child, and he’s not never going to be able to have life or kids or anything," she continued. "But I do want justice, but it’s not going to give me any closure.”

The search for more leads

St. Pete Police Chief, Anthony Holloway said he’s committed to getting Anderson justice for her son. Along with other officers, Holloway met with residents Wednesday, asking for any leads in Oliver’s case and in the shooting death of 58-year-old Rodney Bascom, who was found shot near 11th Avenue last week.

“We’ve got some good leads, but we want to continue to build on those leads," Holloway said.

Officials said they were able to solve two other recent murders with help from the community. It's their hope the murders of Oliver and Bascom might be solved in a similar fashion.

"You know, someone told us this and we’re trying to add on, so we complete the puzzle, so to speak and that’s why we’re out here today,” Holloway said.

If you have any information about these two murders, contact 727-893-7780 or text SPPD+, or send over a tip to TIP411.
