An arrest in Allegheny County starts a process most people have never had to navigate before and hope never to face again. Understanding how that process actually works, rather than relying on assumptions from television, is often the first real advantage a defendant has in the days that follow.

The Three Stages of a Pittsburgh Criminal Case

A Pennsylvania criminal case generally moves through three stages. The first is investigation and arrest. The second takes place before a Magisterial District Court, which handles the preliminary arraignment and preliminary hearing. The third moves to the Allegheny County Court of Common Pleas, the Fifth Judicial District, where pretrial motions, discovery, trial or a guilty plea, and any appeal take place. Each stage serves a different function, and confusing one for another is a common source of unnecessary anxiety for defendants and their families during an already stressful time.

Preliminary Arraignment

After an arrest, a defendant is brought before an issuing authority for a preliminary arraignment. At this stage, the judge does not question the defendant about the alleged offense. Instead, the judge reads the criminal complaint, informs the defendant of the right to counsel and the right to a preliminary hearing, and, where the offense is bailable, sets the type and conditions of bail. The defendant receives a copy of the complaint at this proceeding. Following a warrantless arrest, the law requires that this arraignment happen without unnecessary delay, and certain lower-level misdemeanor cases may allow release on a summons rather than a full arraignment. Where a defendant remains in custody after a warrantless arrest, a judicial determination of probable cause must generally occur within forty-eight hours.

The Preliminary Hearing

At the preliminary hearing, the Commonwealth carries the burden of presenting a prima facie case, meaning enough evidence to establish that a crime likely occurred and that the defendant likely committed it. This is not a determination of guilt, and it is not the trial. The defendant has the right to cross-examine the Commonwealth’s witnesses, and the magisterial district judge decides only whether the case should be held over for court. In Allegheny County, this hearing typically takes place within roughly three to ten days of arrest, often at the Pittsburgh Municipal Court Building or at the assigned magisterial district judge’s office, though scheduling varies and should not be treated as guaranteed.

Formal Arraignment and What Follows

If a case is held for court after the preliminary hearing, a formal arraignment generally follows some weeks later, commonly cited as roughly six to eight weeks in Allegheny County, held at the Allegheny County Courthouse on Grant Street in downtown Pittsburgh. At formal arraignment, the District Attorney’s office files the final charges, known as the Criminal Information, and a judge is assigned to the case. A pretrial conference typically follows a few weeks after that, before the matter proceeds toward trial, whether by jury, without a jury, or through a negotiated plea. These timeframes are typical patterns reported by the county’s own public defender resources, not fixed guarantees, and actual scheduling depends on court calendars and the specifics of each case.

Bail and Pretrial Release

Pennsylvania’s bail rules direct the deciding authority to weigh a range of factors: the nature of the charged offense, the defendant’s employment and financial condition, family relationships, length and nature of community residence, age, health, character, reputation, and any history of addiction, prior compliance with bail conditions, any history of flight or escape, prior criminal record, any history of using a false identity, and other information relevant to whether the defendant will appear and comply with conditions. A defendant’s refusal to admit guilt or assist in an investigation cannot be used to justify harsher bail conditions. Pennsylvania’s rules generally favor release on recognizance where appropriate and disfavor using money bail simply to detain someone who otherwise qualifies for release. Bail decisions remain highly fact-specific, and no particular outcome should ever be assumed in advance.

Rights That Apply From the Start

Every defendant has the right to counsel, and an indigent defendant has the right to court-assigned counsel, from the earliest stages of a criminal case. Every defendant also has the right to a preliminary hearing, and the Pennsylvania Constitution establishes a presumption of release for bailable offenses. These rights exist independently of the charge, though how they play out in practice depends heavily on the specifics of the case and the stage it has reached.

Common Charges Seen in Allegheny County

Pittsburgh criminal defense practice covers a wide range of charges, including driving under the influence, drug offenses, theft and retail theft, assault, and firearms offenses. More serious charges, including homicide-related cases, typically route through the Pittsburgh Municipal Court for preliminary arraignment before proceeding through the county system described above. Each charge category carries its own statutory framework, potential defenses, and procedural nuances, which is why a general description of the criminal process, however useful as an orientation, cannot substitute for a case-specific evaluation.

Why Local Knowledge Matters

Allegheny County’s criminal courts operate with their own local rules, scheduling patterns, and practical rhythms that differ from other Pennsylvania counties. Knowing which magisterial district handles a particular case, understanding the practical timeline between arrest and formal arraignment, and anticipating how the Allegheny County District Attorney’s office typically approaches a given charge are all details that come from familiarity with this specific court system, not from criminal law in the abstract.

This article provides general legal information about Pennsylvania and Allegheny County criminal procedure and is not legal advice. It does not create an attorney-client relationship. Timelines described here reflect typical patterns and are not guarantees, since scheduling and outcomes depend on the specific facts and charges involved. Anyone facing a criminal charge should consult a licensed Pennsylvania attorney early, ideally before answering questions, since arraignment can occur immediately after arrest.
