COLD CASE ARREST: man nabbed 18 years after San Francisco street killing – as DNA on dumped hoodie and murder weapon puts him in the frame
New details have emerged in the 2008 murder of a San Francisco man shot once in the face outside a Western Addition housing development – after a cold case arrest in Los Angeles 18 years on.
Derreyl Goode, 40, was taken into custody in South Los Angeles on August 17 and brought to San Francisco on August 24 to face a murder charge over the killing of Jason Mosely.
An arrest warrant affidavit sworn by a retired SFPD lieutenant now working the department’s cold case unit lays out how investigators say they finally tied Goode to the shooting – his DNA on a sweatshirt the gunman dumped as he fled, and a trace on the grip and magazine of the murder weapon that he cannot be ruled out of.
Mosely was standing in front of 520 Fulton Street, the Freedom West housing development, at around 6:10pm on April 27 2008 when a man walked up to him and shot him once in the face. He was pronounced dead at San Francisco General Hospital.
His girlfriend was pregnant with their child.
The affidavit pieces together the killing and the flight from the accounts of four witnesses.
A motorist parked nearby heard the shot, looked up and saw the gunman standing over the body with a handgun pointed down at the victim.
The complex’s armed security guard walked towards the noise and found the shooter running at him around the corner of the building. Investigators say the man pointed a handgun at him from 20 feet and said: “Stay away from me.”
The brave guard drew his duty weapon, fired two shots and chased him out onto Fulton Street before losing him in an alley.
A resident who looked out of his window said he watched the gunman hurl a pistol over a fence into a nearby yard, then run south towards Grove Street peeling off his black sweatshirt as he went.
A second motorist tracked him as he walked from Gough to Franklin Street before one-way traffic forced him to break off.
Everything the shooter shed was found, including a Hi-Point .380 pistol still loaded with eight rounds. Ballistics matched it to the casing in the courtyard and to the copper-jacketed bullet the medical examiner took out of Mosely’s body.
The black hooded sweatshirt turned up in a garbage can at Grove and Gough – the exact corner two witnesses had put the fleeing man on.
The affidavit then turns to the forensics.
A partial DNA profile was pulled from that sweatshirt in September 2010 and logged as an unknown male. In November 2011 it came back as a hit in CODIS, the FBI-run database that compares crime scene DNA against samples taken from convicted offenders and people who have been arrested.
The name it returned was Derreyl Chase Goode.
Nothing appears to have moved on the case for the next eleven years. It was not until November 2022 that it was picked up by Daniel Dedet, a retired SFPD lieutenant hired back part-time as a civilian cold case investigator.
Dedet went after the gun. When the pistol was swabbed in 2008, the lab reported no DNA on it at all. He asked for it to be run again.
This time it worked. A May 2023 report found a low-level DNA mixture on the weapon. In July 2023 a criminalist compared swabs from the pistol grip and the magazine against the sweatshirt profile and concluded Goode could not be excluded as a contributor – while every other DNA profile in the case was ruled out.
That is the finding that appeared to escalate Goode to prime suspect.
Four months later Dedet interviewed the victim’s girlfriend. She told him she had been on the phone to Mosely moments before he died and heard him say he was going to speak to someone he had not seen in a while – then heard him use a greeting she says he kept for one man. Shown a photograph of Goode, she identified him.
She gave investigators a motive. Mosely was in a struggle with another man over control of a crew of neighborhood juveniles, she said, and Goode had been left in charge of the block during a November 2007 drive-by shooting at Freedom West. He was carrying an AK-type rifle and did not fire back. Mosely never let him forget it.
The victim’s mother had told a homicide inspector a version of the same story back in 2010. She said Goode had been shot, was too slow to get his own gun out, and that Mosely laughed at him. She also said she heard Goode boasting at a funeral that he had done it and would never be caught, and that she saw him carrying a gun there.
A search of records by police turned up no report of Goode ever having been shot.
A judge signed the arrest warrant on April 30 2024 but Goode was not arrested until August 17 2026.
District attorney Brooke Jenkins’ office filed a felony complaint on August 26 charging one count of murder, with an allegation that Goode personally and intentionally fired the gun that killed Mosely. That enhancement carries a consecutive term of 25 years to life on top of any murder sentence.
He appeared the same afternoon in Department 9 before Judge Dawn Payne and told the court he is trying to hire a private lawyer. Bail remains at no bail and the arraignment was put over.
He has yet to enter a plea.
The affidavit sets out the holes in its own case.
Two of the witnesses who saw the gunman are dead: the motorist who watched him stand over the body, in 2022; and the security guard who faced him down at 20 feet, in 2021.
The man whose own sweatshirt and necklace lay beside the body, and whose DNA hit in the national database is half the reason the file ever reached Dedet, would not help. He asked for a lawyer when the investigator found him in a Yolo County jail cell in January 2024. Two others said to have watched the killing have never been traced.
Investigators also logged two rival accounts of the murder, each naming a different man. The original homicide detail chased both and exhausted every lead.
And the descriptions do not fit. Witnesses that evening put the gunman between 29 and his late 30s. Goode was 22.
The case continues.
