Parojinog's brother was also among those killed during the raid and his daughter, Vice Mayor Nova Echaves, was arrested.
Meanwhile, lawyer Lawrence Carim, a member of the Parojinogs' legal team, has complained that he was barred from entering the PNP headquarters at Camp Crame to accompany the vice mayor and her bother Reynaldo Jr. who were flown in from Ozamiz early Monday morning.
Officers recovered rifles, cash and illegal drugs at the address, according to provincial police chief Jaysen De Guzman.
Police said none of their officers was hurt apart from one who sustained a minor injury from an explosion.
Since he took office, police have reportedly killed almost 3,200 people in the drug war.
Vice Mayor Parojinog meanwhile was arrested during the operation and were detained in the Ozamiz police office.
Espenido also served as the police chief of the town of Albuera, Leyte in the Visayas where the late mayor Rolando Espinosa was tagged as one of the region's major drug lords.
The Parojinogs were among powerful warlord clans whom President Rodrigo Duterte has named as biggest narco-politicians in violence-plagued Philippines. In the past, Mr. Duterte had accused the mayor of having links with the drugs trade.

Still, Sen. Panfilo Lacson does not see any need to probe the bloody raids on the houses of Ozamiz Mayor Reynaldo Parojinog and his family in the dead of night that resulted in the death of the mayor and 14 others.
In previous interviews, Parojinog said he had launched his own anti-drug campaign in Ozamiz, even before President Duterte started his war on illegal drugs past year.
In his second annual state-of-the-nation address before the joint session of Congress on July 24, Duterte vowed that despite criticism from here and overseas, the government would continue its "unrelenting" and "unremitting" war on drugs.
The police officers were "met with volleys of fire from (the mayor's) security, prompting the Philippine National Police personnel to retaliate", Pacleb said.
The police chief had explained that the bodies were displayed so that their kin could identify them and to encourage people allegedly victimized by the slain suspects to come forward.
Commenting on Sunday's raid, presidential spokesman Ernesto Abella said: "The administration vowed to intensify the drug campaign".
Duterte, who once said he'd be "happy to slaughter" 3 million drug addicts, has been repeatedly condemned over alleged human rights abuses.
