Source: Dallas murder suspect linked to other home health care deaths

Police say the man who murdered an elderly Dallas woman may be responsible for many more elderly victims. The evidence suggests he could possibly be a serial killer.

Currently, 45-year-old Billy Chemirmir is charged with capital murder in one death, but sources tell FOX 4 he may be linked to multiple home health care-related deaths in Collin and Dallas counties.

Chemirmir was being trailed by Plano police in Dallas with an arrest warrant. It was during that arrest that investigators found a jewelry box thrown in a dumpster. The box had the name of the 81-year-old victim who was later found dead in her Dallas home.

Chemirmir was a home health care worker and is being investigated for several home health care-related deaths in Dallas, Plano and Richardson, according to a police source. They say Chemirmir was on the scene of several deaths of people who had home health care and were thought to have died of natural causes.

Plano police were investigating the home health care worker after a family became suspicious he was stealing from their relative and began following him. While conducting surveillance on the 4500 block of Pear Ridge in Dallas, Plano police saw Chemirmir dump a jewelry box and found him with jewelry, cash, and a set of keys.

Police were able to trace the keys and jewelry box back to a home on the 6600 block of Warm Breeze Lane where they found 81-year-old Lu Thi Harris dead from homicidal violence. A source says she was found with a pillow nearby and her makeup smeared.

Two other possible victims have come forward and told police that Chemirmir tried to sit on their chest and smother them with a pillow. Police have connected him to at least one murder and are investigating him for possibly two others.

Chemirir is being held on a $1 million bond. Records show he is in the U.S. illegally and has an immigration hold.
