Possible serial killer in Tampa, Florida, has community on edge and afraid to walk in the night

For nearly a month, there seemed to be a reprieve from the mysterious killings that paralysed Seminole Heights, a community in Tampa.
In the span of 11 days – from October 9 to October 19 – three people had been fatally shot within a one-mile radius in the neighbourhood.
Police knew of no motive or and had no details about who might have carried out the killings, but they warned residents not to walk alone at night.
Foot traffic in Seminole Heights dried up, as fear – and additional police – saturated the neighbourhood. A week went by without incident. Then another week.
Halloween festivities, which seemed all but certain to be cancelled, proceeded cautiously, with Tampa’s mayor and interim police chief joining children to trick-or-treat as a show of faith in the community.

Even as police tried to determine whether they had a serial killer on their hands, daily life in Seminole Heights marched on. Early on Tuesday, however, any renewed sense of security was shattered when a fourth killing occurred, blocks from where the others took place.
