DANIEL GWYNN, CIVIL ACTION

Plaintiff, No. 25-553-KSM v.

CITY OF PHILADELPHIA, JAMES DOUGHERTY, MICHAEL DUFFY, DOMINIC MANGONI, PAUL MCKELVIE, PAUL RALEY, and THOMAS PERKS,

Defendants.

MEMORANDUM MARSTON, J. November 26, 2025 Plaintiff Daniel Gwynn was granted habeas corpus relief nearly thirty years after his wrongful incarceration for the murder of Marsha Smith. The Philadelphia District Attorney’s office (DAO) dropped all charges, and Gwynn, exonerated, was released from custody in 2024. Gwynn now brings a civil suit against members of the Philadelphia Police Department (PPD) and the City of Philadelphia. Defendants City of Philadelphia and Detectives James Dougherty and Dominic Mangoni move to dismiss Gwynn’s claims against Detectives Dougherty and Mangoni, which allege violations of Gwynn’s Fifth Amendment rights against self- incrimination, and Gwynn’s Monell claim against the City of Philadelphia, which alleges wrongful prosecution, conviction, and incarceration. (Doc. No. 17.) Gwynn filed a brief in opposition. (Doc. No. 20.) For the reasons discussed below, Defendants’ partial motion to dismiss is denied. I. FACTUAL BACKGROUND Accepting all of Gwynn’s allegations as true, the relevant facts are as follows. Marsha Smith, a squatter, tragically died in a fire at an abandoned apartment building on November 20, 1994. (Doc. No. 14 at ¶ 24.) No witnesses saw the person who allegedly started the fire. (Id. at

¶ 64.) But when detectives interviewed three witnesses who lived in the same abandoned building with Smith, two of the witnesses stated that they fought with a man named “Rick” the day before the fire. (Id. at ¶ 44, 49.) Although each witness gave a significantly different physical description of “Rick” (id. at ¶ 41), the detectives claimed that all three witnesses identified Gwynn’s photo as “Rick.” And the detectives fabricated a story that the witnesses recognized Gwynn from a filler picture for a photo array shown to these witnesses in a previous murder investigation. (Id. at ¶¶ 46–59.) The detectives represented to the prosecutor and the court that this photo array was not saved, so their story could not be verified. (Id. at ¶¶ 66–67.) Years later, as part of Gwynn’s federal habeas corpus proceedings, the court ordered discovery which revealed the photo array did not include Gwynn’s picture, leaving it unanswered why

these detectives showed the witnesses Gwynn’s photo. (Id. at ¶ 46.) Gwynn has never been called or known by the name “Rick.” (Id. at ¶ 63.) Following his identification by these witnesses, Gwynn was arrested in connection with the fire that killed Smith. (Id. at ¶ 83.) The day of his arrest, Defendants Dougherty and Mangoni coerced Gwynn into giving a false statement. (Id. at ¶ 83.) Seventeen hours passed between his arrest and the end of his interrogation. (Id. at ¶ 94.) During this time, Gwynn was handcuffed, deprived of access to an attorney, slept a total of fifteen minutes, and was under the influence of crack cocaine. (Id. at ¶¶ 95–96.) Defendants Dougherty and Mangoni knew Gwynn was in a drug-induced state when they interrogated him. (Id. at ¶ 109.) Yet, they fabricated a false confession and forced Gwynn to sign it.1 (Id. at ¶ 97.) The statement only contained details about the crime known to the police, had internal inconsistencies, and contained misunderstandings about basic facts of the crime scene. (Id. at ¶ 105.) At trial, the prosecution based its case largely on the testimony of the three witnesses who

identified Gwynn as the man named “Rick” and on Gwynn’s coerced confession. (Id. at ¶¶ 110– 15.) The jury convicted Gwynn of first-degree murder, arson, and five counts of aggravated assault, sentencing him to death in November 1995. (Id. at ¶ 116.) Years later, post-conviction discovery revealed that the detectives ignored and deprived Gwynn of evidence that offered a credible alternative theory of guilt. (Id. at ¶ 31.) This alternative theory related to the murder of Glenn Taylor, who was killed in the same abandoned house as Smith just fifteen months earlier. (Id. at ¶¶ 117–20.) Witnesses to this murder named the attackers as Maurice Johnson, a/k/a “Reese,” and Gary Lupton a/k/a “Rick.” (Id. at ¶ 128– 31.) Johnson and Lupton threatened to kill the squatters if they gave the police information about Taylor’s murder. (Id. at ¶ 134.) Despite this threat some of the squatters provided

information to the police which then led to the arrests of Johnson and Lupton. Following Johnson and Lupton’s arrests, there were three arson attempts on the squatters’ building, the same building where Smith had lived. (Id. at ¶ 143.) Significantly, two of those squatters—who later identified Gwynn as “Rick”—testified at Lupton’s trial for the murder of Taylor. (Id. at ¶ 141.) It was just three days after these two squatters testified at Lupton’s trial, that the abandoned building where the two squatters lived with Smith was burned down. (Id. at ¶ 142.) Moreover, a separate apartment building of another witness who testified against Taylor and

1 The confession stated that Gwynn argued with the squatters in the building the day before the fire and came back the next day to apologize, but, while there, he dropped gas cans on the hallway and accidentally dropped a match that he was using to light his crack pipe. (Doc. No 14 ¶¶ 84–87.) Lupton was also set on fire. (Id. at ¶ 155.) This second fire occurred after Gwynn’s arrest and while he was in custody. (Id. at ¶ 157.) Post-conviction discovery also revealed a letter to the police from a witness reporting that Lupton (a/k/a “Rick”) solicited him to kill witnesses located in the building where Smith died.

(Id. at ¶ 160.) And, post-conviction discovery showed that the police knew of the connection between the Taylor murder investigation and the arsons because the investigating detectives overlapped and documentation related to Taylor’s murder was found in the Smith murder file. (Id. at ¶¶ 163–69.) But none of this exculpatory evidence was disclosed to Gwynn. (Id. at ¶ 162.) According to Gwynn, the misconduct that occurred in the investigation of his case was the product of a City policy, practice, and custom of unconstitutional misconduct including: • Engaging in unlawful interrogation of suspects; illegal witness detentions and interrogations; fabrication of witness and suspect statements; and failing to record and disclose exculpatory evidence;

• Failing to appropriately discipline or take corrective action against police officers who engaged in illegal or unconstitutional conduct;

• Failing to properly train and supervise officers on the constitutional limitations on their investigative, detention, and arrest powers;

• Ignoring, with deliberate indifference, systemic patterns of police misconduct and abuse of civilians’ rights during police investigations and prosecutions of criminal suspects and defendants, including unlawful police interrogations, illegal arrests, unlawful coercion of witnesses, providing unlawful fraudulent financial rewards for statements favorable to their theory of the case, falsification and fabrication of evidence, and suppression of exculpatory and impeachment evidence; and

• Failing to properly sanction or discipline PPD officers, who are aware of and conceal or aid and abet violations of constitutional rights of individuals by other PPD officers, thereby causing and encouraging PPD officers, including Defendants in this case, to violate the rights of citizens such as Mr. Gwynn.

(Id. at ¶ 217.) Gwynn alleges the City and its policymakers knew about these practices, and in support of that allegation, references 1977 and 1978 Philadelphia Inquirer Pulitzer Prize-winning reports, governmental investigations, complaints, and internal PPD investigations. (Id.
