MIAMI — A South Florida man stabbed his ex-girlfriend's 11-year-old daughter and tried to make her death look like a suicide, according to police.
Miguel Ruiz Lobo did not get along with Martha Guzman, Miami police Chief Manuel Orosa said Monday.
"She convinced her mother to dump him," Orosa said.
The girl's mother, Amaury Alvarenga, found her June 25 with a knife in her throat.
Police tell the Miami Herald that Lobo tried to make the slaying look like a suicide but sliced through tendons in the girl's wrists, which would have made it impossible for her to stab herself in the throat.
According to police, DNA found in skin under Martha's fingernails has been matched to Lobo. Lobo was held Tuesday without bail on charges of first-degree murder and burglary.
Alvarenga filed a petition March 31 with Miami-Dade County Circuit Court to place a restraining order against Lobo.
Acting Circuit Court Judge Judith Rubenstein initially denied the petition, ruling that "there is no appearance of an immediate and present danger of domestic violence."
Alvarenga's request was denied for a final time April 14.
