San Diego police have arrested a suspect in connection with a fatal stabbing downtown on Saturday night, authorities said.

The stabbing was reported shortly after 9:20 p.m. in front of the Hotel Churchill near the intersection of C Street and Eighth Avenue, police said.

When officers arrived, they found the victim, described as a man in his 40s, on the sidewalk suffering from apparent stab wounds. Officers and medics rendered aid, but the man died before he could be taken to a hospital, police said.

Witnesses directed officers to the suspect, who had retreated into a nearby apartment and was trying to start a fire inside the unit, said homicide Lt. Lou Maggi.

Officers forced their way into the room and used a police dog to subdue the man, identified as 34-year-old Grant Parker, who was taken into custody. Parker was taken to a hospital before being transported to the central jail, where he is being held without bail on suspicion of murder, according to online jail records.

Investigators said the relationship between Parker and the victim is not known.

The investigation prompted a halt to trolley service downtown for several hours on Saturday evening because the crime scene was near the trolley tracks, the Metropolitan Transit System said on X. Police said the trolley service has been restored.
