2016 Interaction with Juvenile
A lawsuit claimed Alvarado grabbed a 14-year-old Hispanic boy by the neck and "slammed his head against the ground and concrete". It was alleged that Alvarado also threatened to have the boy and his family deported.
The Sheriff’s Office said that Alvarado’s actions were "reasonable under the circumstances".
The case was settled for $15,000.

On July 16, 2020, Brooks' family filed a lawsuit in U.S. District Court, citing violations of the Fourth, Fifth, Eighth, and Fourteenth Amendments, and state laws.
On September 24, 2020, the case was dismissed. Jefferson Parish had requested that the case be dismissed, and Brooks' family did not file a timely objection, even though they were represented by counsel. 
2021 Interaction with Shantel Arnold
The Sheriff’s Office said it opened an internal probe into the deputy’s actions shortly after the incident.
In September 2022, the Sheriff's Office determined that Alvarado's actions were "both reasonable and acceptable" because of Alvarado's belief that Arnold was intoxicated and because her skin was slippery.
