Two additional people have been arrested in connection with a grisly Markham home invasion last November that was allegedly staged.

York Regional Police announced the arrest of two suspects on Friday, alleging the men participated in a targeted family home invasion in which two victims were tied up and shot.

The victim's daughter was already arrested in connection with the home invasion.

"It is the belief of the investigation that these two individuals did enter the residence and commit these horrendous crimes," Det. Sgt. Larry Wilson told a press conference on Friday.

Bieh-Ha Pan, 53, was killed in the incident, while her husband, Huei Hann Pan, 57, suffered serious injuries after being shot.

The couple's daughter, 24-year-old Jennifer Pan, has been charged with murder and attempted murder.

Police were called to the family's Helen Avenue home on Nov. 8 2010 at about 10:30 p.m after receiving a 911 call.

Police found Bieh-Ha Pan dead inside the residence. Her husband was also found at the home with serious injuries.

"The citizens of Markham and the Region of York should know that this was not a random act. They will be relieved by the fact that we have made arrests in this matter," York Regional Police Supt. Wayne Kalinski said on Friday.

David Mylbaganam, 22, and Eric Carty, 31, both of Toronto, were arrested and charged with first degree murder, attempted murder and conspiracy to commit murder.

Wilson said Mylbaganam was arrested Thursday night in Toronto's Jane and Finch area. Carty was arrested at the Maplehurst Detention Centre, where he is being held on unrelated charges.

Pan remains in custody on charges of murder, attempted murder and conspiracy to commit murder.

York Regional Police officers continue to investigate the incident and expect to make further arrests.

"I urge the persons involved in the heinous crime to seek legal council and turn themselves in immediately," Wilson said.
