Authorities investigate shooting of Miami-Dade woman and death of former partner

Dalianis Lazo, 41, was shot by her former partner at a home in Country Walk in southwest Miami-Dade County on Thursday, October 22. She was taken to Jackson South Medical Center and remained in serious condition. The Miami-Dade Sheriff's Office Homicide Bureau identified 53-year-old Iván Granado as the alleged shooter.

Deputies went to the home after receiving a report of gunfire. Authorities' preliminary assessment is that Granado shot Lazo after an argument and then took his own life. Investigators are treating the case as an alleged attempted murder followed by suicide while examining the circumstances surrounding the attack.

Investigators said the man did not live at the residence and had not determined a motive. The Sheriff's Office identified Granado as the alleged gunman while detectives continued reconstructing what happened at the Country Walk home and the events preceding the shooting.

Lazo had requested a restraining order against Granado in April, according to Miami-Dade court records. The request was denied September 30, 22 days before the shooting. In her petition, she told the court she feared for her life. That judicial record documents a request involving the relationship before the incident.

The attack occurred at a southwest county residence where deputies arrived after a gunfire alert. Authorities continue investigating it as an alleged attempted murder followed by suicide. Detectives have not established a motive and said Granado did not reside at the home. Lazo remained hospitalized in serious condition.
