The Nebraska Humane Society says another dog has been poisoned in the backyard of an Omaha couple.
Three-year-old Murphy became violently ill only minutes after being let into the backyard earlier this month.
A urine test came back positive for strychnine, a type of poison.
Two dogs died in November after eating tainted meat in the same backyard. The meat was laced with the same type of poison.
There is a $2,500 reward offered for information regarding this case. If you believe you have any useful information contact the police.
