Perez Vizcaino is one of 10 suspects detained in the case.
About two days after the shooting, Ortiz was in stable enough condition to travel to a hospital in Boston, where he is still recovering.
Ortiz was shot in the back at point-blank range as he sat with friends on the patio of the Dial Bar and Lounge on Sunday, June 9, in what appeared to be an ambush.
This information seems to be close to the hearsay that was provided on Twitter a few days ago about Ortiz "intentionally" wrecking his auto because he feared for his life.
Investigators at the attorney general's office in Santo Domingo said Victor Hugo Gomez was the alleged mastermind.

It was a memorable occasion, with the Toronto Raptors winning the league title on the Golden State Warriors' home court. Thompson couldn't have returned had he not shot the free throws, which gave the Warriors their biggest lead at 85-80.
Alberto Miguel Rodriguez Mota was identified in court documents as the man who meant to pay 400,000 Dominican pesos, roughly $7,800, to hire people to kill Ortiz, multiple media outlets reported.
They said Perez then sold the cellphone used to plan the attack and to distribute a picture of the target to a woman for $180 so he could get rid of the evidence a day after the shooting. Authorities say they are looking for at least three other suspects, including the man they believe paid the hit men. Authorities have said the coordinator of attack was offered 400,000 Dominican pesos, or about $7,800. Doctors in the Dominican Republic had removed Ortiz's gallbladder and part of his intestines before he was flown to Boston for further treatment.
