Police are appealing for information from anyone who saw three men near a Swansea housing estate after a man’s body was found following a garage fire.
Officers were called to Delffordd in Rhos in the early hours of 10 March.
An investigation is underway into the cause of the fire and his death.
Police want to trace anyone who saw three men in the vicinity between 12.15am and 2.30am.
They believe the men arrived in the area by taxi – possibly from Cardiff – and are appealing for the driver of that taxi to come forward.
Officers said he would have picked the men up possibly outside the Hilton hotel, and dropped them in Delffordd.
Anyone with any information is asked to contact police on 101.
