Nassau County’s latest "Mugshot Monday" dropped this week, and it is a five-person lineup that stretches from Uniondale to Mineola. The Nassau County Police Department on Monday shared a social-media roundup naming five people it says are wanted across the county, complete with photos and short physical descriptions. Investigators are asking residents to send in tips and to let officers handle any encounters with the suspects.

Who Nassau Police Are Looking For

According to the Nassau County Police Department, the post names five individuals wanted on a range of allegations.

The lineup includes Jefferson Mendoza of Uniondale, who is wanted for a violation of Nassau County probation, and Tyshanay Jackson of Hempstead, who is wanted on a second-degree assault charge alleging intent to cause physical injury with a weapon.

Police say they are also looking for Devone Medlock of Baldwin, sought on attempted second-degree assault charges involving an injury to a child under 7, and Luis Alonso Ulloa Chavez of Westbury, wanted on a public-lewdness allegation. Rounding out the list is Frank Coscetta of Mineola, named on stolen-auto and third-degree grand larceny counts.

Each of the five entries in the "Mugshot Monday" post includes a brief physical description to help the public identify the individuals.

How To Submit Tips

If you know where any of these individuals might be, Nassau County Crime Stoppers runs an anonymous tip line at 1-800-244-TIPS and accepts web tips through its site, with rewards of up to $5,000 for information that leads to an arrest, per Nassau County Crime Stoppers.

Police say residents should call 911 for immediate sightings or threats. Non-emergency leads can be sent to local precincts or shared through the Crime Stoppers portal.

Why Mugshot Monday Exists

The weekly "Mugshot Monday" push is part of the department’s social-media strategy to widen the audience for cases involving suspects who have missed court dates or violated release conditions. The posts typically pair photos with short case notes and town names to spark tips and community leads, a tactic that has produced results in past cases.

Not everyone is a fan. The same posts that help track down people who, police say, are evading the court process also draw critics who argue that these public lineups can stigmatize certain neighborhoods and residents.

Police Advisory And Legal Note

Alongside the mugshots, the department’s post explicitly warns residents not to try to apprehend or detain any of the named individuals and to report any information directly to police.

It is also worth remembering that being listed in a wanted roundup is an allegation, not a conviction. All of the named suspects are presumed innocent until proven guilty in court, and any updates on arrests or changes to the charges will come from Nassau County police or through court filings.
