Gonzalez-Lopez’s and José L. Rodríguez-Sánchez’s (collectively, “Plaintiffs”) son, Christian José Rodríguez-González (Rodríguez), who was shot and killed during a police chase carried out by Defendants Officer Alberto Robles-Concepción (“Robles”) and Officer Emanual Ramos-Pabón (“Ramos”) on July 15, 2022. Plaintiffs Monica E. Gonzalez-Lopez and Jose L. Rodriguez-Sanchez (collectively, “Plaintiffs”) filed a motion _in limine_ to preclude the testimony of [Janeliz Rodriguez](https://expertwitnessprofiler.com/expert-witness/Janeliz-Rodr%C3%ADguez%20Disla/1572032), an expert for Defendants Municipality of San Juan, Mayor Miguel A. Romero-Lugo, Commissioner Juan J. Garcia, Alberto Robles-Concepcion, and Emmanuel Ramos-Pabon. ## **Forensic Expert Witness** [Janeliz Rodriguez Disla](https://expertwitnessprofiler.com/expert-witness/Janeliz-Rodr%C3%ADguez%20Disla/1572032) possesses a Bachelor’s in Criminal Justice; a private detective certification from a forensic college at which she now teaches; numerous certificates in evidence analysis, evidence handling, forensics, and forensic photography; over fourteen years of work experience, including in analyzing security camera videos; several licenses as a private investigator; and experience in at least three federal court cases involving the forensic analysis of videos and photos.

In the case at bar, the Court found that Rodriguez’s description of a “long and dark object” as “consistent with being a long weapon or rifle,” is admissible because Rodriguez is qualified to so characterize the object on account of her qualifications in forensic video analysis and criminal justice and her work experience as a detective and investigator. Moreover, even assuming Rodriguez was not an expert, her testimony regarding the object is unremarkable and perception-based observation, which the case law permits even lay witnesses to offer. The Court found that Defendants have shown that Rodriguez possesses the qualifications and work experience necessary to analyze the video in question and to make the comparison challenged by Plaintiffs. ## **Held** The Court denied Plaintiffs’ motion_ in limine_ to preclude the testimony of Janeliz Rodriguez. ## **Key Takeaway** The characterization of a “long and dark object” as “consistent with being a long weapon or rifle” is admissible as a run-of-the-mill observation about the object’s purported visible shape and silhouette. The statement challenged by Plaintiffs does not identify technical specifications such as make, model, operability, or any other such ballistics-based assertions. This sort of ordinary description is rationally based on perception, in line with the strictures of even [Fed. R. Evid. 701](https://www.law.cornell.edu/rules/fre/rule_701). Moreover, the fact that the statement includes the qualified phrase “consistent with”–in place of a more definite assertion that the “long and dark object” is certainly a weapon–further militates in favor of admitting it. ## **Case Details:** --- ## **You Might Also Like** ![Corrections Expert's Standard of Care Testimony Admitted](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/04/blog-pic-640X480-2026-04-23T161938.085.jpg) [**Corrections Expert’s Standard of Care Testimony Admitted**](https://expertwitnessprofiler.com/forensic-expert-was-allowed-to-opine-on-the-objects-purported-visible-shape-and-silhouette/corrections-experts-standard-of-care-testimony-admitted)![Human Resources Expert Allowed to Opine on Termination](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/04/blog-pic-640X480-2026-04-22T200052.311.jpg) [**Human Resources Expert Allowed to Opine on Termination**](https://expertwitnessprofiler.com/forensic-expert-was-allowed-to-opine-on-the-objects-purported-visible-shape-and-silhouette/human-resources-expert-allowed-to-opine-on-termination)![Neuropsychology Expert Not Allowed to Opine on Cognitive Decline](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/04/blog-pic-640X480-2026-04-22T144728.528.jpg) [**Neuropsychology Expert Not Allowed to Opine on Cognitive Decline **](https://expertwitnessprofiler.com/forensic-expert-was-allowed-to-opine-on-the-objects-purported-visible-shape-and-silhouette/neuropsychology-expert-not-allowed-to-opine-on-cognitive-decline)![Human Factors Expert Not Allowed to Opine on the Tile](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/04/blog-pic-640X480-2026-04-21T191749.960.jpg) [**Human Factors Expert Not Allowed to Opine on the Tile**](https://expertwitnessprofiler.com/forensic-expert-was-allowed-to-opine-on-the-objects-purported-visible-shape-and-silhouette/human-factors-expert-not-allowed-to-opine-on-the-tile)![Insurance Expert Not Allowed to Opine on Legal Duties](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/04/blog-pic-640X480-2026-04-21T155751.487.jpg) [**Insurance Expert Not Allowed to Opine on Legal Duties**](https://expertwitnessprofiler.com/forensic-expert-was-allowed-to-opine-on-the-objects-purported-visible-shape-and-silhouette/insurance-expert-not-allowed-to-opine-on-legal-duties)
